BMW Installation Instructions

The installation time is approx. 4 hours, but this may vary depending on the condition of the car and the equipment in it.

Important information

Only for use in the BMW dealer organisation.

Ensure that the cables/lines are not kinked or damaged as you install them in the car.

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

Use cable ties when routing cables. Tie back any excess lengths.

Subject to technical modifications.

Before you install the retrofit system, test the control module status with the CIP (coding, customising, programming) test program. If the test detects incorrect statuses in one or more control modules, these must be updated first using the “Load software” function.

5.To install the retrofit

When fitting the ultrasonic converter holders and the ultrasonic converters D, make sure that the

ultrasonic converters D are aligned with their connection sockets pointing towards the middle of the bumper trim (1).

Mark the midpoint within the marks (1) and centrepunch it. Drill holes (2) (Ø27 mm).

Use a suitable tool to create anti-rotation locks (3), at the same time observing the prescribed alignment of the ultrasonic converters (see Fig. 085 0023 V).

Insert the ultrasonic converter holders C into the holes.

The detents (1) must engage. If necessary, chamfer the holes from the inside of the bumper.

Insert the ultrasonic converters D.

The detent hooks on the ultrasonic converters D must engage.

Push cable ties and holders E onto the plastic projections (1).

Then fit the converter wiring harness into the bumper trim and connect it to the ultrasonic converters (not illustrated).

[1]Insert the grommet (1) for the converter wiring harness B into the body recess.

Route the converter wiring harness B into the boot.

Use plastic nuts H to fit the PDC control unit F onto the holder G.

Connect the plug (1) of the converter wiring harness and branch A1 of the PDC wiring harness into the same coloured plug casing on the PDC control unit F.Thread the holder G into lug (2) and fasten it with a plastic nut H.Route the PDC wiring harness along the right door sill to the front in the area below the A pillar on the right.

Connect branch A2 to the earth bolt X1106 (1).

Plug branch A3 into the free slot in the joint connector X10116 (1) with colour WSRTGE.

Connect branch A4 to PIN 13 of plug X11007 (1) on the power distributor.

In cars not fitted with a gong I, cut out the recess (1) along the embossed mark on the inside of the pedal trim (2).

Clip the gong I into the recess (1) in the pedal trim (2).

Attach the cable connectors and cables with cable

ties. Select the installation route of the cable so that it cannot be damaged by moving parts. Route branch A5 into the driver’s footwell.

Plug branch A5, 1-pole socket casing, into slot T4 X363.

Plug branch A6, 3-pole socket casing, into slot T3 X522.

In cars with a gong I fitted, branch A6 is not required and can be tied back.

Cars without a gong only

Connect branch A7 to the earth bolt X9633 (1).

Route branch A8 into the passenger’s footwell.

Cars without a gong only

Connect branch A8 to PIN 22 of plug X254 (1) on the base module (2).

6.Concluding work and coding

The parking distance control (PDC) retrofit requires coding.

  • Connect the battery, connect a charger
  • Program/code the parking distance control (PDC) retrofit with DISPlus or GT-1 using the CIP application and follow the instructions in the program
  • Conduct a function test
  • Re-assemble the car
