1. Important information
(Only for use within the BMW dealer organisation.)
Installation time approx. 7.5 hours.
The installation times may differ depending on the condition of the car and the equipment in it.
This retrofit system may only be installed with a headlight cleaning system.
All servicing, repair, installation and adjustment work on cars is conducted on your own responsibility.
All work is to be completed using the latest BMW
–Repair instructions,–Circuit diagrams,
–Service manuals,–Work instructions,
–Diagnostics manuals
in a rational sequence using the prescribed tools (special tools) and pursuant to the relevant health and safety
regulations.
Safety notes
An optional equipment wiring harness is used on the E53. This means that if a car is fitted as standard with at
least one of the following pieces of special equipment (SA), the other modules (MD) for the special equipment on
this level will also be integrated in the vehicle wiring harness.
The modules for the special equipment for the lower levels will then also be available.
Example: If a car is fitted with SA 536 (auxiliary heating system), all models on level 3, level 2 and level 1 will be
available.
Level 2
SA 235 (MD AHM) (trailer hitch)
SA 502 (MD SRA)
SA 508 (MD PDC)
SA 609 (MD navigation system)
SA 624 to 629 (US SA 640 (MS car telephone / radio)
Level 3
SA 248 (MD steering wheel heating system)
SA 261 (MD rear airbag)
SA 265 (MD RDC) (tyre pressure control module)
SA 461 (MD backrest heating system in the rear)
SA 496 (MD seat heating system in the rear)
SA 533 (MD rear air conditioning)
SA 536 (MD auxiliary heating system)
Level 4
SA 220 (MS single axle level control)
Level 5
SA 522 (MD automatic headlight adjustment control system / xenon lights)
Safety information
These installation instructions are only valid for LHD cars.
All lock nuts are to be replaced.
All tightening torque values are to be taken from the current repair instructions and must be observed at all times.
Ensure that cables and other lines are not kinked or damaged when they are being installed in the car and that
they do not impair the freedom of movement of other components.
If the specified pins or chambers are already in use, bridges, double crimps or parallel end stops are to be used.
Do not use so-called ”Scotchlock connectors" since they may cause faults in the vehicle's electrical system.
