Important information
Licensing regulations
If the towing hitch is installed in the Federal Republic of Germany (FRG) it must undergo an acceptance test pursuant to § 19 of the Road Traffic Act, performed by an official testing body such as TÜV or DEKRA and then also be entered in the vehicle documents. If the towing hitch is installed outside the FRG, the relevant licensing regulations of the country must be observed.
Installation information
All work is shown on a LHD car.
Remove the underseal from all the points at which the towing hitch is in contact with the body. Then clean the areas with washing benzene. Coat bare metal body parts with anti-corrosion paint.
Deburr the edges of all holes and treat them with anti-corrosion paint. Remove all drill chips.
Do not kink or damage the cables during the installation work since otherwise they may cause faults that can later only be identified and rectified by extensive additional work. The costs incurred as a result of this will not be reimbursed by BMW.
If the specified PIN's are occupied, bridges, double crimps or twin-lead terminals must be used.
Target group
The target group for these installation instructions is specialist personnel trained on BMW cars with specialist knowledge of vehicle electrical systems.
Work:All servicing, repair and installation work on BMW cars is completed at your own risk.All work is to be carried out using current BMW- Repair manuals- Circuit diagramsin a rational order using the prescribed tools (special tools) and observing current health and safety regulations.
