Instrument Cluster SwappingPrerequisites: The new or used cluster is installed in the car. Battery voltage at least 12.0 V. All relevant coding and adaptation values have been transferred from the OLD (ORIGINAL) cluster to the REPLACEMENT (NEW or USED) cluster. Immo 3 Audi vehicles typically use adaptation channels 060, 061 and 062 for the internal installation list since they do not have address 19-CAN Gateway. If in question, run a complete AdaptationControl Module Mapwith the old module installed. Immo 3 VW vehicles typically use short coding in address 19-CAN Gateway. If the original value is 00006, which is common, recode the new unit to the same value to refresh the internal gateway installation list. Make sure to have BOTH PIN's, from the OLD (ORIGINAL) and the REPLACEMENT (NEW or USED) instrument cluster. Make sure to have the Radio Code (for factory radios only).

During normal use, the air mass flow meter goes old and also gets soiled. This causes difference between the stored characteristic and the set status which in turn leads to problems like less power or black smoke. To prevent this, the Air Mass Flow Meter adaptation function has been brought into the DDE5.

Function:The DDE control unit does the Air Mass Flow Meter adaptation at two working points: during idle and underload with operation specifications as follows:Engine speed=1700 3000 rpmCharge Air Pressure=1100 2800 mbarSpeed=90 160km/hrChange in intake air temperatureCOM* adapter.

I am prompted to write this short guide due to the general misinformation and unjustified 'fear' people seem to have with regard to the Siemens/VDO immobiliser and it's use in the T4 1.9TDI conversion. In short, if it worked in the donor car then there is absolutely no reason why it should not work in your van.

Before I give a detailed description of the Siemens/VDO type immobiliser (commonly known as Immobiliser 2) as fitted to most late 94->2000 VAG cars, here's a quick overview:

Passive Immobilisation

The introduction of passive vehicle immobilisation by the major car manufacturers came about because the brokers for the Insurance Federation of Germany began to refuse to underwrite vehicles that did not have passive electronic immobilisation systems fitted. The use of the word 'passive' meant that no direct intervention was required by the user to 'activate' or 'deactivate' the system. Some of you may remember Peugeot marketing an immobiliser in their vehicles in the 1990's which required the user to input a PIN on a keypad before starting the vehicle - this is an example of an 'active' system as it requires user intervention.

So how does VW Immobiliser 2 work?

The passive Siemens/VDO transponder system fitted to most VAG group cars at least between late 1994 and 2000 comprises of three primary components: 1) The immobiliser control unit, 2) The key (a transponder or RFIC device - you may hear people call it a 'chip') embedded within the body of the key or fob, and 3) The key reader antenna attached to the ignition barrel. The immobiliser 2 control unit interacts with the ECU and instrument cluster, (and body electronic systems on some vehicles). It is important to note that the key is paired (or matched) to the immobiliser not the ECU.

The Siemens/VDO immobiliser control unit:

The transponder RFIC (found inside the key):

The key transponder reader antenna array:

When an attempt is made to start the vehicle, the control unit transmits a burst of RF (Radio Frequency) energy at a given frequency - to the key reader antenna around the ignition barrel. The RFIC or 'chip' in the key contains a tuned circuit which is matched to the frequency of this burst of RF, as a result a small voltage is then generated by induction within the transponder device. This small amount of induced RF energy is used to charge a capacitor, which is used to power the RFIC device. The RFIC then responds by transmitting (again by RF), a unique individual thirty two (32) digit identifier (number). This all happens seamlessly and in microseconds, so the user never noticesIf the immobiliser 2 unit 'recognises' the identifier transmitted by the RFIC as a 'known' vehicle key, it then sends a message to the ECU to allow it to be 'unlocked' and hence allow the vehicle to start. A common sign of a faulty immobiliser system is that the vehicle will start but will only run for 1 or-so seconds.The two main manufacturers in immobiliser transponder (RFIC) technology are Philips (see pic above), and Texas Instruments - both of which are used on VAG vehicles. Although it is Philips devices which are used in most of the immobiliser 2 systems.

So what do I need to know when wiring the immobiliser for the 1.9 TDI conversion?

From the donor car, you will need:

1) Siemens/VDO immobiliser control unit (as pictured above),2) Original key (or RFIC device from the key as shown in pic above - not strictly required, but makes life easier - see FAQ )3) Key transponder reader4) The ECU.

There are two connectors on the control unit:

One is a 3 pin connector the other is 6 pin.

* The 3 pin goes to the transponder key reader antenna array.* The 6 pin connector is numbered (as you can see) pins 1 to 6

So starting at the start:

Pin 1 - Black , connect this to an ignition switched +12v supply

Pin 2 - Grey/white, goes to the ECU (pin 61 for Bosch 68-pin ECUs)

Pin 3 - Grey goes to the OBD II diagnostic socket, but changes to a grey and white at the diagnostic socket end.

Pin 4 - Brown, ground

Pin 5 - Not connected

Pin 6 - Brown, ground

Pin 1 was originally connected to the donor vehicle instrument cluster and got it's +12v supply from there.If you removed the cluster( therefore no +12v to pin 1) the immobiliser will not function - engine will start and run for a second and then stop.

Alternatively, if your donor vehicle came with the above immobiliser (usually made by TEMIC or Sagem, but Siemens/VDO also made them), then usually they will have an 8-pin connector for the power and diagnostic functions rather the the six pin connector outlined above it is connected as followed:

Pin 1 = B+ (12V)

Pin 2 = +12_IGN

Pin 3 = N/C

Pin 4 = GND

Pin 5 = GND

Pin 6 = N/C

Pin 7 = Engine k-line

Pin 8 = k-line diagnostic socket

FAQ

1. Is there any way I can bypass the immobiliser

Simple answer: 'No' otherwise this would defeat the purpose of the manufacturer fitting an immobiliser to begin with.

More complex answer: 'Yes' - you can have the firmware of the ECU modified such that it does not expect to receive a message from the key via the immo box thus doing away with the immobox reader coil and key altogether. This can be expensive however ~85GB at the time of writing (11/2010).

Another "solution" is to fit a immobiliser emulator, which are available from a 3rd party companies, cost at the time of writing is about 55. However it may just cheaper and easier to buy a key/immo box pair from a local scrapyard

Personally, I do not understand why anyone would want to remove the immobiliser. It will after all make your van harder to steal which for me at least is a always a bonus.

2. I bought an engine/harness/immobiliser but I didn't get any key/key was lost/incorrect etc.. Is there any way I can get a new key(s) programmed?

Yes, some locksmiths/dealers/independents will do this but only if you have the SKC (Secret Key Code - comes on a tag with the car when it was new - most have long since been lost). Others locksmiths/dealers/independents can do it without the SKC, but they charge accordingly ~50-80.

If you have the SKC and a fully registered copy of VAG COM/VCDS you can do it yourself.

Alternatively, for a small fee (strictly to cover costs), If you send me the immobiliser I can extract the SKC from your immo box so that new keys can be coded to your immobiliser, or if you send me a new key I can adapt that to the immo. (PM me for details)

Troubleshooting

You will not be able to do any diagnosis without a copy of VAGCOM to interrogate the immobiliser

The immo system (apart from a power supply) essentially depends on two things: 1) A good signal from the key and 2) A reliable link to the ECUThe only way to test the integrity of these is with VAGCOM

When installing the antenna (which is often incorrectly described as a coil because of its shape),you should never put the key 'in-the-middle' of the antennato test the immo, this will only result in a poor/no signal to the immo box. The best way to ensure a reliable signal is to fit the key reader to the ignition barrel in the van and the correct transponder to the key. The reason for this is that the RF signal that the transponder generates is so small that positioning is critical. In addition to this, the ignition barrel acts as a ground-plane for the antenna array to improve the propagation of the transponder signal. VAGCOM will report 'intermittent of poor signal from key' type faults if you problems in this respect.

If you have problems with the datalink k-line to the ECU, then either the immo will report a comms failure or the ECU will give you a 'Engine start blocked by Immobiliser'.

Hope this helps with understanding and wiring of the immobiliser system and clears up any mystery that surrounds the 'magic' of VW immobiliser 2.Removed/Reinstalled Instrument Cluster - Now Immobilizer Will Not Let Car Start

I removed my instrument cluster two weeks ago, had some LED work done on it, and have reinstalled. Now the Immobilizer-3 light blinks, and when I try to start the car, it does the typical running for 2 seconds and dies.

I followed the troubleshooting found here:http://www.myturbodiesel.com/1000q_h...mmobilizer.htm

Specifically, I've done the following with no success:

- Charged up my battery and checked voltage is greater than 12.5 V (I still have the original OEM battery with 86,000+ miles and 6+ years on it)

- Tried to start the car with both of my keys/fob

- Leaving the key in the ignition to "ON" but not start for a few minutes to see if the immobilizer light would stop flashing

- Disconnecting BOTH negative and positive terminals of the battery, and then touched the cables to each other for about 1 minute, while not attached to the battery

- Ran VCDS, which gave me plenty of faults related to the immobilizer

End ---------------------------------------------------------I just ordered a VAG Tacho 2.5 shipped from Northeastern U.S.

For my problem, I'm not sure which of the procedures in the following link I must follow:http://www.myturbodiesel.com/1000q_h...ulti/immo3.htm

Choices are:

- Procedure for matching keys to vehicles with Immobilizer in the Instrument Cluster

- Procedure for adding keys to vehicles with separate Immobilizer

- BRAND NEW ECU (doubt this one, since I did not swap my ECU)

- Used ECU (doubt this one, since I did not swap my ECU)

- Procedure for installing a NEW Instrument Cluster in vehicles with Immobilizer III (doubt this one, since I did not swap my instrument cluster)

Can anyone help, PLEASE!!!__________________Links:2003 Jetta GLS TDIwith DeutschlandGnther-Tunespecific to my performance modifications-Platinum GrayThe original codes were probably stored as a result of turning the car on when the instrument cluster was not in the vehicle or not properly installed, as the CAN gateway and the Immobilizer are all physically present in the instrument cluster.

Clearing the codes and trying it again seems to have pointed to the issue : The immobilzer donut (black circular thing around ignition key slot) has having an issue reading the key. The donut cannot read the RFID key tag, therefore it can't compare that value to the values stored in the EEPROM as authorized keys.

Easy stuff: I'd verify that the connectors on the instrument cluster are plugged in properly for starters. I'm assuming they are, they are pretty hard not to get correct.

Second, I'd look for damaged pins in the cluster housing and damaged pins or wires on the connectors going to the cluster. I gave up my MkIV Bentley, so I have no wiring diagrams, however the donut has a connection to the cluster.

If neither of those work, I'd see if you can get your hands on another Immo3 instrument cluster, even temporarily. Your car will likely not start, but it would tell you if the donut that reads the keys are still having issues. (You'd get a code about unauthorised key if the donut can read a key when connected to a different cluster, not a signal too low from key.) This will determine if you have a cluster problem or an immo donut problem. Any 1J0 920 xx6 cluster or 1J5 920 xx6 cluster will suffice for this test, gas or diesel, etc..

I say try a new instrument cluster first as I'm assuming you did nothing while the cluster was down and out to the wiring or connections to the immo donut or anything else in the steering column. Depending on what resources are available to you, it might be easier for you to trace down the wiring from the cluster to the immo donut than get your hands on another instrument cluster.

If you did happen to be poking around in the steering column, ensure that all the grounds are good. There's a grounding post in there that has a bunch of brown wires connected to it. Make sure it's not tarnished / corroded and that the screw/bolts are tightened.

This is a crappy situation.

BTW: Do you happen to know your 4 digit Immo SKC?__________________- Don'97 Jetta TDI - 135K - R.I.P. 10/22/03'03 Jetta TDI - Silver / Black Leather, 161K miles - Sold.'09 Jetta TDISedan - Sold!'14 Passat TDISEL - Blue / Black LeatherAs for your proposed solution, I don't think this is going to be the smoking gun fix.

The cluster isn't saying the key isn't authorized, it's saying that the signal from the key is too low to get a reading. Re-Matching keys isn't going to do you much good if the immo donut / cluster can't get the ID number from the key. See where I'm going with this? If the keys had become unmatched you would get a fault indicating "Unauthorized key". This means that it successfully read the ID from the key, however it did not match one of the key IDs that were in the EEPROM as adapted.

If the ground for the Immo donut is weak or bad, it would cause this issue. Broken wiring as well as a bad donut would also cause this fault.

The Immo donuts have been known to go bad on occasion, and there was an issue in early NBs with Immo with some kind of a loose connection or bad immo reader causing the same conditions you are seeing.

It could be coincidence that your Immo donut went bad at this time, however it's pretty unlikely. Thats why my first suggestion would be to get a new cluster, then to trace wiring. If no other cluster is available, check wiring.__________________- Don'97 Jetta TDI - 135K - R.I.P. 10/22/03'03 Jetta TDI - Silver / Black Leather, 161K miles - Sold.'09 Jetta TDISedan - Sold!'14 Passat TDISEL - Blue / Black Leather VW and Audi key, remote, and immobilizer FAQ and troubleshootingThis FAQ article describes how the immobilizer system works, how to replace the smart key in your VW or Audi remote, and troubleshooting steps/and how to bypass/delete the system.

The immobilizer is a theft deterrent system located in the instrument cluster, the main car computer, a radio frequency identification (RFID) transponder chip in the VW or Audi smart key, and an antenna at the ignition cylinder. You cannot do an immobilizer bypass with normal "car theft" tools so don't bother asking. If your VW is 1999 or earlier and sold in North America, it shouldn't have an immobilizer. If your car has the yellow car/key symbol on the instrument cluster when you turn the key to "ON", (shown activated below) it has an immobilizer. This light comes on for a second but quickly goes out when turning the car on and all is normal. If it stays on, you have an issue.

When buying or programming a new key, you must use a key that corresponds to the same immobilizer generation and keyless entry type and sync it to the immobilizer. If you need a new key, read the summary below and refer to the detailed instructions at1000q: mk4 key programmingor1000q: mk5 key/remote FAQ. If you have an Audi A3, the steps in VW mk5 mostly apply. If you have a mk3 VW you don't have an immobilizer if you're in North America but here's1000q: mk3 key programming FAQanyways. Audi have the same immobilizer systems but in different generations than VW so the same general procedures apply.

The main symptom of a faulty system or activated immobilizer is that the engine shuts off after a second or the yellow car/key symbol on the dashboard flashes. A very low car battery or car battery removal could also cause the immobilizer to become active. On rare occasions it's triggered for unknown reasons - see the rest of this page for troubleshooting. Below is a video demo of the immobilizer shutting off the engine. If it doesn't act like this it's not the immobilizer. See the starter troubleshooting pages.

The immobilizer chip has a range of about 1" through plastic and about 3" when out of the key (bare chip). Although the computer constantly monitors if the chip is correct or not, it won't shut off the engine after the first few seconds of the car engine starting. I'm almost certain that it won't shut off the engine if the chip signal is interrupted after a few minutes. (I didn't want to test it by driving around without the chip signal). If you want to be very careful, don't let the key get exposed to high strength microwaves. Standing next to a microwave won't do anything but putting the key into a microwave will damage the chip. One nice thing about the immobilizer system is that if a key is stolen/lost, having the keys reset by the dealer or someone with the correct key matching tools will prevent the lost key from operating the car as normal. After the keys are reset, the old metal key can still open the doors and start the engine but the immobilizer won't let the engine run for more than 1 second. Because of this, when you reset the immobilizer, all keys must be present or else the old ones won't work as intended anymore.

The first step in getting a new Audi or VW Smart Key / remote key fob

The remote has 3 main components: the keyless entry circuit board, the metal flip key to open the doors and insert into the ignition, and the immobilizer chip which talks to the immobilizer. Each is a separate system. The immobilizer chip is glued in the flip key half and cannot be purchased from VW separately. You can buy them on ebay as the megamos chip. Each must be correct for the Smart Key to work as intended. For example, even if you buy a cut metal key, the unprogrammed immobilizer chip will shut the engine off after a second. The immobilizer has nothing to do with unlocking the doors, the alarm, or the starter - it still lets you start the engine but if it's not programmed it will shut the engine off.

Here is a mk4 key 1998-2009. As you can see, the immobilizer chip (white arrow) uses no battery - it's an RFID chip energized by the pick up antenna on the ignition coil.

2010 and newer keys look like this. They changed the key to work with KESSY, the keyless entry and start system. Even if you don't have KESSY, the key still looks like this. The immobilizer chip is the long black rectangle soldered to the board. At this time, I have no idea where to buy the chip by itself.

-If the car has no immobilizeryou can program the keyless entry yourself and have a new key cut anywhere which does a "reverse cut" side milled key found on VW - Audi. Again, if your instrument cluster doesn't have the yellow car/key symbol you don't have immobilizer.

-If the car has an immobilizer and you have an existing broken key(broken remote or flip key), remove the immobilizer chip from the old key and swap it into another new or used key to prevent the immobilizer from acting up. The chip looks like a small grain of rice, pictured above and below. Then you can program the keyless entry yourself. If you need a new metal key, just take the key apart and swap the bad switchblade key with a new cut one. You can cut the new metal key anywhere which does side mill/reverse cut/laser cut VW - Audi sidewinder keys.

-If the car has an immobilizer and you don't have an old keyto salvage the chip out of, you must read the notes below about the SKC code and key variations.

For generation specific information on keys including how to take them apart, refer to the links at the top or search this FAQ. Audi followed different generations but the articles will work for them.

How to use a remote starter with an immobilizer equipped carRemote starters still require a valid immobilizer signal just like a regular key. If you buy a remote starter system, make sure it has the relay signal box approved for VW/Audi signals. You must place the key or just the half with the chip inside the relay box. The relay box is then hidden somewhere in the car. When you use the remote starter, it relays the immobilizer signal inside the hidden box to the antenna around the ignition cylinder ring and works like OEM. They will work with any 1998-present system.

How the immobilizer works and immobilizer differences by yearIf you have the yellow car symbol pictured at the top on the instrument cluster, you have an immobilizer. When you turn the car on, the antenna around the ignition switch induces a voltage in the RFID transponder chip. When the key is recognized, the immobilizer module, part of the instrument cluster, sends a random number to the key. The module and key both do a simple calculation and if they match, normal engine starting is allowed. Immo 3 also tells the ECU to do a calculation. Because of this, you can swap ECU on immo2 cars but not immo3 or above.

The three main types of TDI immobilizer are immo2, immo3, and immo4. VW up to 1999 sold in North America don't have an immobilizer. Cars sold in Europe or the rest of the world may have immobilizer 1. These used a separate physical immobilizer box. 1999-2000 should have immo2. 2001-2005/6 use immo3. 2005/6-present use immo4. Around 2010, VW keys changed their design even though they still use immo4. As of this writing, immo5 is only found on the newest Audi. Immo2, 3, 4, and 5 keys are not compatible. In other words, if you have an immo2 car, you can only use an immo2 key because the chip is different.

Immo 4 uses no module - the immobilizer is a function built into multiple parts.

As late as 2001, there were some B5 Passat that didn't have any immobilizer. All Jetta, Golf, and Beetle definitely had them by this point.

Cabrio and Eurovans have no immobilizer warning light and the immobilizer module is a separate physical box from the instrument cluster.

Telling the difference between immobilizer 2 and 3If your car is in a transition year and you're not sure if you have immobilizer 2 vs. 3, connect a ross tech VCDS to the obd2 port and access the immobilizer module. Go to measuring block 81. If you see your VIN number it's 100% not immobilizer 2.

-If you have no immo- you can swap keys, ECUs, and instrument clusters without any special programming. This assumes that the part numbers and software coding (settings) are the same.

-If you have immo2- you need the SKC to use a new key or instrument cluster but you can swap the ECU without any special programming. It has an emergency drive function that will let you drive to the dealership or mechanic for them to fix but you must know the SKC code. You can buy a used key and it will work if you reprogram the immobilizer chip using the SKC.

-If you have immo3- you need SKC to use a new key, instrument cluster, or ECU. You cannot use used keys from another car since the immobilizer chip can only be set once to a car (unless you swap out the chip with your current one). Again, the chip-key half is separate from the remote keyless entry half.

-If you have immo4- found on mk5 and mk6 Volkswagens and newer Audi. You need SKC to use a new key, instrument cluster, or ECU. You cannot use used keys from another car since the immobilizer chip can only be set once to a car (unless you swap out the chip with your current one). Same restrictions as immo3.

-Immo5- found on 8T generation Audi A4 (2007/2008+) and 8k generation Audi A5 (2007+).

The cheapest and easiest way to get a replacement VW or Audi Smart keyBecause of the variation in build dates, immobilizer generations, and remote compatibility, the easiest way to get a replacement key is from the dealer. Dealers are expensive but they can match the key to the car and if it's the wrong part they'll take it back. If you buy an ebay replacement key for an immobilizer car you have to figure out how to program the immobilizer, if your car was a transition year, and there are no refunds once you cut a key. Some won't touch ebay keys.

The cheapest way to get a new key from the dealer is to buy a cut key from an online OEM parts dealership and take it to the local dealer for programming. The online dealership can cut it if they have your VIN number. Regardless of the number of keys, they typically charge for 1 hour even though it really only takes less than 15 minutes of actual work. If they charge you for 1/2 hour, it's very fair. The smart key immobilizer must be programmed in person with someone who has access to the SKC.The part numbers below are only a guide, double check the correct part number with your parts vendor, this website is not responsible if you order the wrong key!

The absolute cheapest way to get a new key is to buy the programming tools yourself, buy a cut key online, and when you're done, resell the programming tools. The initial investment in the tools isn't cheap and most people end up keeping their VCDS tool since it's so useful. If you can get the dealer to only charge a half hour for programming, that is the cheaper route.

NOTE: The newest keys 2007+ on most VW models and all 2010+ keys use additional encryption on the immobilizer chips. As of this writing, there are no aftermarket tools to program the immobilizer key yourself. In this case you must to go to the dealer. Technically speaking, you can use a qualified locksmith as a result of a class action lawsuit about smart keys but these specialized shops are few and hard to find. Due to the expensive equipment they have to rent from VW, they're usually not any cheaper than the dealership.

-If you have a car with build date 11/98-09/00, (about model year 1998-2001) your remote probably looks like#1pictured below, part number should be VW# 1j0 959 753 f-If you have a car with build date 10/00- 05/01 (about model year 2000-2002), you probably have the remote that looks like#1, it should be VW# 1j0 959 753t.

-If you have a car built after 05/01 (about model year 2001-2002), you should have remote #2, it is either VW# 1j0 959 753 am or 1j0 959 753 dc

-If you have an mk5 body VW up to around 2006-2007, you have immo4, your Jetta remote is either VW# 1j0 959 753p, or 1k0 959 753h.

-If you have a mk5-mk6 body VW 2010+ your key is a new style and you can't do much with them since there are no aftermarket tools to get the SKC. Go to the dealer.

How to disable or bypass the immobilizer system in your VW or AudiLong story short, you have to bench flash the ECU with new programming to completely delete the immobilizer system. The immo light will still blink but the car will always start.. If you have an immo2 car and know the SKC code you can do an emergency bypass so that you can drive to the dealer. You can also order bypass boxes online. I've never used one since I've never had to and they are reported to be buggy/not always work.If it was too easy and fast to bypass it wouldn't be a very effective anti theft device, would it?

If you wish to remove the immobilizer function from the car you can only do this through a specialized chip tune. This requires you to remove the ECU from the car and ship it to eitherKermaTDIorMalone Tuningwhere it's bench flashed and rewritten. When seeking an immobilizer delete, make sure to include any requested ownership information to verify the status of the car. As a bonus, they can also do a power upgrade at the same time.

Problems that are NOT related or caused by the immobilizer system-If the starter does not engage or the engine does not "turn over" at all, this is not an immobilizer problem. You probably have an ignition switch or starter problem. For mk3 and mk4 cars, see1000q: starter FAQ and troubleshooting. For mk4 Passat, see1000q: B5 Passat starter fix. For mk5 Jetta or Golf, see1000q: mk5 starter.

-If your car shuts off more than 3 seconds after engine start it has nothing to do with the immobilizer. The immobilizer shuts the engine off in the 1st second.

-The chip inside the key does not have a battery or other internal electricity source. It's an RFID chip and is "excited" by the antenna around the ignition switch. Shaking the key or changing the remote fob's battery will not fix any problem with the immobilizer. Just look at the pictures above - there are no batteries for the immobilizer chip. In the case of the 2010 and newer keys, if the battery dies you just hold the key next to where the ignition should be. The RFID signal will still be read.

-The immobilizer system has nothing to do with opening or unlocking the doors. The immobilizer will not be activated by the alarm system - the alarm system affects the starter. The immobilizer's ONLY action is allowing the engine to stay running a second after starting it. Again, the keyless entry and immobilizer are separate.

-It has nothing to do with the power of the car. If your car has poor performance or fuel economy, it has nothing to do with the immobilizer. See1000q: limp mode for the TDIand1000q: constant low power or can't revfor more details.

More detailed information below is separated into immo-2 and immo-3 sections because they have different procedures. I'm working on an immo-4 section, please refer to immo-3 and your bentley manual for now. Remember, to work with the immobilizer, you MUST have a vag-com/VCDS tool. You cannot use a generic code scanner, you must use a VCDS cable. You can only use an emergency start without a VCDS and even then you must know the SKC code.Basic immobilizer troubleshooting1.First, make sure the car battery is charged. A low battery can cause problems with the immobilizer. It also results in low cranking RPM during engine start - this will cause the ECU to prevent fueling.

2. Try another key - you should have a valet key and spare key that also have an immobilizer chip in them. If they work, then you have isolated the problem to the key. Again, there is NO battery for the immo chip, it gets power from the ignition switch transmitter. You can try reprogramming the chip with the procedures linked to below.

3. Check for error codes - scan the car with a VCDS to see if there is a problem with the system and refer to the appropriate procedure below.

4. You can try just leaving the key in the ignition to "ON" but not start for a few minutes. Many people report that the light just goes away after 10 minutes as if nothing ever happened. This and the next solution appear to have something to do with a capacitor discharge or something resetting. It sounds strange but many report that it works.

5. Disconnect the battery negative terminal and step on the brake pedal - this turns on the brake lights and discharges any stored electricity. This may reset the immo system. I've heard that disconnecting BOTH negative and positive terminals of the battery and then touching the cables to each other only, while not attached to the battery can also reset it. I think that it takes more time and does the same thing as disconnecting the negative side and turning on the brake lights. Again, don't touch the cables to the battery, touch them only to each other while both are disconnected from the battery - you don't want to short the battery out.

6. Check wiring and plugs at instrument cluster and pickup coil at the ignition switch, there is a chance it could be faulty. You could try wiggling the key in the slot in case there's a problem with the pickup coil. However, the range of the antenna/chip is about 1" so it's definitely not a range problem.

7. Put a trickle charger on the battery, put the key to the "ON" position and leave it for a few hours. If it didn't reset after 10 minutes it's been known to reset after a few hours and never appear again.

This chip is pictured below. It's not possible to bypass the immobilizer with normal "car theft" tools so don't bother asking. If you have an immobilizer 3 key you can only replace it with an immobilizer 3 key. If you're looking only to replace the VW smart key, see1000q: VW key/remote FAQfor more details. This page details the other parts of the immobilizer system and immobilizer 3 specific procedures.

The main symptom of a faulty immobilizer system is the car shutting off after two seconds or the anti-theft light on the dashboard flashing. A very low car battery or battery removal could also trigger the immobilizer. Some people report certain computers with wireless internet activated in the car interfering with the transmitter in the key of the immobilizer. If you want to be super careful, don't let the key get exposed to high strength microwaves. Standing next to a microwave won't do anything but putting the key into a microwave will quickly damage the chip (and possibly the microwave).For immo3: you need SKC to use a new key, instrument cluster, or ECU. You cannot use used keys from another car since the immobilizer chip can only be set once per car. The reason why is because it uses a rolling immobilizer code instead of a simple transmit 1 code like earlier systems.The immobilizer chip has a range of about 1" through plastic and about 3" when out of the key. Although the computer constantly monitors if the chip is correct or not, it won't shut off the engine after the first few seconds of the car engine starting. I'm pretty sure that it won't shut off the engine even if the chip signal is interrupted during driving. (I don't want to test it by driving around without the chip signal).

VW Smart key replacement part numbersThe part numbers below are only a guide, double check the correct part number with your parts vendor, this website is not responsible if you order the wrong key!-If you have a car with build date 10/00- 05/01 (about model year 2000-2002), you probably have the remote that looks like#1, it should be VW# 1j0 959 753t.-If you have a car built after 05/01 (about model year 2001-2002), you should have remote #2, it is either VW# 1j0 959 753 am or 1j0 959 753 dc, it should have immo 3. You don't have immo 4 unless you have an mk5 car.

Telling the difference between immobilizer 2 and 3If you still can't figure out if you have immobilizer 2 or 3, use a ross tech VCDS to access the immobilizer module. Go to measuring block 81. If you see your VIN number it's 100% not immobilizer 2.

A blank message prevents any help and if that's what you want, that's what you will get.Using a remote starter with your car despite the immobilizerRemote starters will work but they must have a booster box approved for the VW/Audi chip. You put the key or chip inside the booster box and hide the box in the car. When you use the remote starter, the booster box uses the immobilizer chip in it to pass a valid signal to the immobilizer antenna on the ignition coil pickup. It will then work like any other remote starter. Make sure that the car is in park or neutral (if manual) whenever using a remote starter.Problems that are NOT related to the immobilizer system-If the starter does not engage or the engine does not "turn over" at all, this is not an immobilizer problem.-The chip inside the key does not have a battery or other internal electricity source because it is an RFID chip and is "excited" by the transmitter. Shaking the key or changing the remote key's battery will not fix any problem with the immobilizer.-If your car shuts off more than 3 seconds after engine start it has nothing to do with the immobilizer as explained in thegeneral immobilizer FAQ.-It also has nothing to do with opening or unlocking the doors. The immobilizer will not be activated by the alarm system, it only has to do with starting the car.-It also has nothing to do with the power of the car. If your car has poor performance or fuel economy, it has nothing to do with the immobilizer.See1000q: limp mode for the TDIfor more details.This article is separated into immo-2 and immo-3 sections because they have different procedures. Immo-4 general overview is also included, troubleshooting procedures are similar to earlier cars. Note that to work with the immobilizer, you MUST have a VCDS. You cannot use a generic code scanner, you must use a VCDS cable. You can only use an emergency start without a VCDS. and even then you must know the SKC code.Also note that immo-2 and immo-3 keys are not compatible. If you have an immo-2 car, you must use an immo-2 remote/key.General troubleshooting procedures for immobilizer 31. First, make sure the car battery is charged. A low battery can cause problems with the immobilizer. It also results in low cranking RPM during engine start - this will cause the ECU to prevent fueling.2. Try another key - you should have a valet key and spare key that also have an immobilizer chip in them. If they work, then you have isolated the problem to the key. Again, there is NO battery for the immo chip, it gets power from the ignition switch transmitter. You can try reprogramming the chip with the procedures linked to below.3. Check for error codes - scan the car with a VCDS to see if there is a problem with the system and refer to the appropriate procedure below.4. You can try just leaving the key in the ignition to "ON" but not start for a few minutes. Many people report that the light just goes away after 10 minutes as if nothing ever happened. This and the next solution appear to have something to do with a capacitor discharge or something resetting. It sounds strange but many report that it works.5. Disconnect the battery negative terminal and step on the brake pedal - this turns on the brake lights and discharges any stored electricity. This may reset the immo system. I've heard that disconnecting BOTH negative and positive terminals of the battery and then touching the cables to each other only, while not attached to the battery can also reset it. I think that it takes more time and does the same thing as disconnecting the negative side and turning on the brake lights. Again, don't touch the cables to the battery, touch them only to each other while both are disconnected from the battery - you don't want to short the battery out.6. Check wiring and plugs at instrument cluster and pickup coil at the ignition switch, there is a chance it could be faulty. You could try wiggling the key in the slot in case there's a problem with the pickup coil. However, the range of the antenna/chip is about 1" so it's definitely not a range problem.7. Put a trickle charger on the battery, put the key to the "ON" position and leave it for a few hours. If it didn't reset after 10 minutes it's been known to reset after a few hours and never appear again.

ProceduresMirrored from ross tech's siteRecoding a new key without a VCDS OR recoding it with a VCDSWhen you buy a replacement key, you must have it matched to work with the immobilizer. The remote unlock/lock, etc., has nothing to do with the immobilizer, so that must be matched separately. You can either use a VCDS to recode it or you can take the old key apart and just remove the old RFID chip and put it in your new key. The RFID chip is just glued in place, there are no batteries for the chip. The only batteries are for the remote unlock.To reuse the existing immobilizer chip, pop it out (pictured below) and swap it with the new key's chip. Use some water based glue to help hold it in place. See1000q: mk4 key FAQfor a detailed procedure, this article is more about the immobilizer.Image of key disassembled - note that the immobilizer chip (white arrow) uses no battery - it is energized by the pick up antenna on the ignition coil.

Recoding a key with VCDS - mirrored fromross tech's siteThis procedure details how to match new keys to Immobilizer-equipped VW/Audi vehicles. As of 11 Mar. 2002, VW and Audi are providing 7-digit Secret Key Codes in place of the earlier 4-digit SKC's. Keys must be coded using the new 7-digit SKC (secret key code) method unless the owner still has the correct 4-digit code.Procedure for matching keys to vehicles with Immobilizer in the Instrument Cluster:(includes many 1999+ Golf/GTI/Jetta/New Beetle/Passat, also Audi)1.

This works similarly to Immobilizer II, except a secret key code (SKC) is required in order to perform the adaptation routine. The routine changes depending on whether you are using a BRAND NEW ECU that has never been in any other car, or if you are using a USED ECU that has been previously matched to another car.Immo-3 knows your car's VIN. Access 17-Instruments (or separate 25-Immobilizer on vehicles that are set up that way) and look at the first "Extra" field.
