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.

Seal slots 1, 4 and 5 using the supplied blind grommets.
Only for cars with a level control system:
Cars with a level control system already have a branch of the vehicle wiring harness to the level sensor at the
rear right and a black 6-pin plug X1451.
Disconnect the three cables in the car (yellow/brown, yellow/grey and yellow/white or yellow/black) and connect
them as follows to the black 6-pin plug X1451 (I) supplied with the parts kit:
On cars with air suspension on one axle:
Connect the yellow/black cable to slot 1 of the black 6-pin plug X1451 (I).
Connect the yellow/brown cable to slot 4 of the black 6-pin plug X1451 (I).
Connect the yellow/grey cable to slot 5 of the black 6-pin plug X1451 (I).
On cars with air suspension on both axles:
Connect the yellow/brown cable to slot 1 of the black 6-pin plug X1451 (I).
Connect the yellow/grey cable to slot 4 of the black 6-pin plug X1451 (I).
Connect the yellow/white cable to slot 5 of the black 6-pin plug X1451 (I).

Seal the hole in the floor of the boot with the grommet (H).
Ensure that the grommet (H) is fitted so that the car is watertight and that the cables do not interfere with any
other components.
G
Only for cars with an optional equipment wiring harness above level 2 (see section 1):
Lay branch J, yellow/white cable, parallel to branches I1to I3(see Figure E) into the boot. Lay branch Jon the
wiring harness along the battery positive distributor, continue behind the boot trim (10) to the 6-pin plug X1310S
(11). Cut branch J, yellow/white cable, to size and connect it to the yellow/white cable from slot 2 of the 6-pin plug
X1310S (11) using the double mini connector supplied in the parts kit (see magnified view).
Drill two holes in the boot trim (10) and secure branch Jto them using cable ties (12) (see magnified view).

footwell to the left-hand side of the car, through the additional passage hole in the front bulkhead grommet (13)
and the grommet (14) into the engine compartment and then along the vehicle wiring harness on the inside wing
to the 42-pin blue plug X1170 (15) on the ABS/DSC control module.
The left front bulkhead grommet (13) does not have an additional passage hole for retrofit wiring harnesses in
the first cars in the series. In this case the cable Jis to be laid along vehicle wiring harness through the front
bulkhead grommet (13).
EN/2-51

Disconnect the 42-pin blue plug X1170 (15) from the ABS/DSC control module, release the plug strip, remove the
blind stopper from slot 18 and connect branch J, yellow/white cable, to slot 18.
Engage the plug strip, connect the 42-pin blue plug X1170 (15) to the ABS/DSC control module and secure it.
J
Lay branches K1to K3, black/white, black/grey and black/green cables, through the additional passage hole in the
right front bulkhead grommet near the electrics box and then through the grommet (16) into the engine compart-
ment. Lay branches K1to K3along the vehicle wiring harness on the inside wing towards the front and to the
engine near the washer water tank.
The right front bulkhead grommet does not have an additional passage hole for retrofit wiring harnesses in
the first cars in the series. In this case the cables K1to K3are to be laid along vehicle wiring harness through the
front bulkhead grommet.
K
Lay branches K1to K3parallel to the cables for the ABS sensor into the wheel arch and connect them to the
black 6-pin plug X10275 (K) as follows:

Cars with air suspension on both axles only:
Two black/white and two black/grey cables are used. it is therefore essential to keep to the order described to
avoid confusion.
There is already a black 6-pin plug X10275 in the car. Disconnect the three cables (black/brown, black/grey and
black/white) from these plugs and connect them to the black 6-pin plug X10275 (K) supplied in the parts kit as
follows:
Connect the black/brown cable for the air suspension to slot 1 of the black 6-pin plug X10275 (K).
Connect the black/grey cable for the air suspension to slot 4 of the black 6-pin plug X10275 (K).
Connect the black/white cable for the air suspension to slot 5 of the black 6-pin plug X10275 (K).
Connect the cables on the xenon wiring harness as follows:
Connect branch K1, black/white cable, to slot 2 of the black 6-pin plug X10275 (K).
Connect branch K2, black/white cable, to slot 3 of the black 6-pin plug X10275 (K).
Connect branch K3, black/white cable, to slot 6 of the black 6-pin plug X10275 (K).
All cars:
Connect the black 6-pin plug X10275 (K) to the level sensor at the front right (17) and secure the wiring harness to
the hole in the axle with a cable tie (18).
Check again that the entire xenon wiring harness has been installed in such a way that none of the cables
are kinked or damaged and that it has been secured with the cable ties so that it does not interfere with any other
components.
