Installation time

The installation t ime is approx. 4.5 hours, but may vary depending on the condition of the car and theequipment in it .

As a matter of principle, the cars firmware must be flashed to the latest I stage status before starting thework. Depending on the production age of the car and the work already carried out on the car, theprogramming t imes will vary, which means that we cannot quote a specific t ime at this point.

The installation t ime does not include any time for programming/encoding, as this depends on the ageof the car and the equipment in it.

Important informationThese installation instructions are primarily designed for use within the BMW dealership organisation

and by authorised BMW service companies.In any event, the target group for these installation instructions is specialist personnel trained on BMWcars with the appropriate specialist knowledge.All work must be completed using the latest BMW repair manuals, circuit diagrams, servicing manualsand work instruct ions, in a rational order, using the prescribed tools (special tools) and observing currenthealth and safety regulations.

In the event of any installation or function problems, restrict the troubleshooting session toabout 0.5 hours for mechanical work or 1.0 hours for electrical work.

Do not archive the hard copy of these installation instructions since daily updates are made by ASAP!

Pictograms

denotes instructions that draw your attention to dangers.

Denotes instruct ions that draw your attention to special features.

Denotes the end of the instruct ion or advisory text.

Ordering instructions

On cars with 6-cylinder petrol engines (N52) and automatic gearbox, the 400 W electric fan mustbe replaced with a 600 W electric fan (see EPC for part number and further details) .If you do not replace the electric fan, the towing capacity will be reduced and the engine maystop.

Installation information

For E90 cars built before 07.03.2005 the 26 mm mounting bolts must be replaced withhexagonal screws Z supplied.

Before installation, the build status of the fuse box should be tested in accordance with TIS RA 61 13 ...(Interior fuse box for cars built before 09/2005 ).

Ensure that the cables/lines are not kinked or damaged as you install them in the car. Costs incurred asa result of this will not be reimbursed by BMW AG.

Addit ional cables/lines that you install must be secured with cable ties.

If the specified PIN chambers are occupied, bridges, double crimps or twin-lead terminals must be used.

All pictures show LHD cars; proceed accordingly on RHD cars.

After the installation work the retrofit kit must be programmed / coded via the Retrofit/CIP

path.

Legal requirements

A type approval in accordance with EC Directive 94/20/EC Annex VII exists for the towing hitch, withEC homologation mark e13*1709

.

If you comply with these regulations and notes in theseinstallation instructions, no special acceptance test pursuant to 19 of the German Road TrafficLicensing Directive and no special entry in the vehicle registration document is necessary.

15. Statutory regulations pursuant to EC Directive 94/20/EC

Appendix VII

Regulations for the homologation of a vehicle for the optional installation of mechanicalconnection devices (towing hitches)

1. General regulations

1.1The vehicle manufacturer determines which types and classes of connecting devices can be fitted ontothe vehicle type, and specifies the values D, V 1, S or U (if applicable) which are based on the design ofthe vehicle type in combination with the planned type of connect ing devices. The code values D, V, S orU of the connect ing devices approved in accordance with this direct ive must be greater than or equal tothose specified for the vehicle type in question.

1.2The connect ion devices must be installed on the vehicle type in accordance with the installation

instruct ions specified by the vehicle manufacturer and in compliance with the manufacturer of theconnection device and the Technical Service. The vehicle manufacturer shall define the permittedpoints for securing the connect ion devices to the vehicle type and, if necessary, the mount ings,installation plates, etc. that must be mounted on this specific vehicle type.

1.3Only automatic hitches are allowed to be used for hitching up t railers with a total mass of more than3.5 tonnes to motor vehicles; these automatic hitches must permit an automatic hitching procedure.

1.4When connecting devices of class B, D, E and H are fitted to trailers, it is always necessary to assume avalue of 32 tonnes for the total mass T of the towing vehicle in order to calculate the D value. If the Dvalue of the connecting device for T = 32 tonnes is not sufficient, the resultant restriction relating to themass T of the towing vehicle and the mass of the vehicle combination (towing vehicle and trailer) mustbe specified in the approval sheet for the trailer.

1) The V value must only be specified for vehicles with a technical gross weight in excess of 3.5 tonnes.

BMW AG, Munich 01 29 0 399 825 7/2007 (T/Z) 32


2. Special regulations

2.1Fitt ing coupling balls and towing brackets (ball head with towing hitch)

2.1.1When coupling balls and towing brackets are fitted to a vehicle type of class M1, class M2 below 3.5tonnes and class N1, the clearance and height dimensions shown in the figure 1and 2must bemaintained. This requirement does not apply to off- road vehicles in the sense of Appendix II of Directive92/53/EEC. Unspecified details are to be selected to suit the appropriate purpose. The dimensions andangles must be checked using suitable measuring instruments.

2.1.2The vehicle manufacturer must supply installation instructions for coupling balls and towing brackets.These installation instructions must specify whether the attachment area requires reinforcing.

2.1.3It must also be possible to couple and uncouple coupling heads when the longitudinal axis of the

coupling head in relation to the centre line of the coupling ball and towing bracket:

a) is turned horizontally through b = 60 to the right or left (see Figure 2)

b) is rotated vertically through a = 10 upwards or downwards (see Figure 1)

c) is rotated axially through 10 to the right or left.

2.1.4The mounted coupling ball must not obscure the rear registration plate or the space provided for the rearregistration plate; otherwise, a ball that can be removed without requiring special tools must be used.

2.2 Installing tow ball couplings2.2.1Class B coupling heads are permitted to be used with trailers of a gross mass up to 3.5 tonnes. Tow ballcouplings are to be installed in such a way that the coupling point of the trailer when the trailer is hori-zontal and with a permitted axle load is 430 mm 35 mm above the horizontal wheel contact level (seeFigure 3). The horizontal position for caravans and trailers is the posit ion in which the floor or the loadingbed is horizontal. On trailers without a reference area of this type (for example boat t railers or the like)the manufacturer of the trailer must specify a suitable reference line to define the horizontal position.The required height only applies to trailers that are to be coupled to the vehicles listed in 2.1.1.

2.2.2It must be possible to operate coupling heads safely within the clearance of the coupling ball as shown

in figures 1and 2.
