Important information
The retrofit kit is for use within the BMW dealership organisation only.
Target group
The target group for these installation instructions is specialist personnel trained on BMW cars
with specialist knowledge of body electrical systems.
All work is to be carried out using current BMW
- Repair manuals (see Technical Information System),
- Circuit diagrams (see Diagnostics Information System),
in a rational sequence with the prescribed tools (special tools) and taking into account the
relevant health and safety regulations.
Installation information
The retrofit wiring harness is to be installed so that it cannot kink or chafe.
If the specified PIN chambers are occupied, bridges, double crimps or twin-lead terminals must
be used.
All work is shown on a LHD car. On RHD cars some work must be completed the opposite way
round.
All tightening torque values are to be taken from the current repair manuals and must be
observed.
Safety instructions
The current accident prevention regulations must be followed.

8. To assemble the car
Assemble the car again following the instructions for its dismantling in reverse order.
9. Coding
To ensure that the PDC retrofit system adjusts to the specific car perfectly the PDC control
module must be coded. The Mobile Diagnostic Computer MoDIC (III) or the DIS with CD version
15 (or higher) is required to code the PDC control module. It cannot be coded with an older
version.
The steps for this procedure are described briefly below:
Connect MoDiC (III) to the diagnostics plug in the car and switch on the ignition.
Ensure that there is sufficient battery voltage during the coding procedure, connect a
battery charger if necessary."
Select menu point “Coding/Program.”
After completing the coding switch off the ignition for approx. 10 seconds."
