Important notes

Target Group

Target group for these installation instructions are technical personnel trained on BMW vehicles, who have special knowledge of body electronics.

Tasks:

Carry out all maintenance, repair and installation work on BMW vehicles on own authority.

All operations should be carried out with the aid of the current BMW

– repair instruction manuals – circuit diagrams in a logical sequence using the prescribed tools (special tools) whilst observing the applicable health and safety regulations.

Assembly notes

All operations are shown on a left-hand drive vehicle. On right-hand drive vehicles, proceed in the same sequence but in mirror image.

Should specified pin spaces be already assigned, bridges, double crimping or parallel connections will have to be made.

Take care to see that cables do not get kinked or damaged when they are being installed as otherwise faults may occur which can only be localised later by extensive reworking. Costs arising in this way will not be reimbursed by BMW.

Tightening torques for screwed connections should be observed. Please refer to the parts information system (TIS) for the required tightening torques.

Required tools and ancillary materials

Set of flat-tip screwdrivers
Set of Phillips screwdrivers
Set of TORX wrenches
Hand lamp
Drilling machine
Set of hexagon-socket screw keys (Allen keys)
Set of 1/2 inch socket wrenches
Crimping pliers for AMP contacts

4. Install cable set GRA/MFL and connect

Unplug green, 10-pole connector X10170 from the switch support (1). Install cable set GRA/MFL along the series wiring harness (2) to the connector X10170. Decouple connector X10170 and plug in branch cables A1 – A3 as follows: A1, cable colour yellow/black, in Pin 8 A2, cable colour white/grey/yellow, in Pin 9 A3, cable colour violet/yellow, in Pin 10

Install branch cables A4 – A6 behind the heater/air conditioner to the glove box.

Install branch cable A6 behind the glove box through the rubber grommet into the E box. Pull out 40-pole connector X60004 from the DME/DDE control unit and decouple it.

Plug branch cable A6, cable colour yellow/black, into Pin 27.

Couple connector X60004 again and connect to the DME/DDE control unit.

Install branch cables A4 and A5 to the light module.

Unplug connectors (1, 2 and 3) from the light module (4).

At the 56-pole connector X10117, cut the following cables approx. 10 cm away from the connector:

Violet/yellow cable (terminal R) coming out of Pin 13 and white/grey/yellow cable (I/K Bus) coming out of Pin 36.

In each case provide the cable ends with an AMP annular and pin contact and put on housing.

Connect branch cable A4, cable colour violet/yellow, to the violet/yellow cable coming out of Pin 13 and connect branch cable A5, cable colour white/grey/yellow, to the white/grey/yellow cable coming out of Pin 36.

5. Install MFL steering wheel

Vehicles with four-spoke steering wheel only

The markings on the steering wheel and steering shaft must match.

Put on existing four-spoke steering wheel (1) and fasten with screw (2).

Observe tightening torque as per TIS.

Put on airbag unit (1) which is supplied with the installation kit and screw it on.

Observe tightening torque as per TIS.

Vehicles with three-spoke steering wheel only

The markings on the steering wheel and the steering shaft must match.

Put on existing three-spoke steering wheel (1) and fasten with screw (2).

Observe tightening torque as per TIS.

Fit existing airbag unit (1).

Observe tightening torque as per TIS.

6. Finalising operations/coding

Fasten all plug-in connectors again and put on connectors.

Reassemble the vehicle in the reverse sequence of disassembly. Carry out a function test.

This retrofit package is not coding-relevant.
