Dismantling and assembling electric window lifters — AUDI

Notes:

The rear electric window lifter is an "open system" and must only be moved if bolted to the door component carrier. Otherwise the electric window lifter will be destroyed. The entire window lifter therefore has to be replaced if repairs are required.
Replacement of the motor/gear unit assembly is described in the following.
The mechanical section (linkage/cable) is replaced in the same way. The upper door stop must then be adjusted.

To secure in position, use cable ties to tightly connect metal housing cover and plastic cover at both cable exits -arrows-.

Note:

Both cable ties may be left in place throughout the entire sequence of repair operations, since servicing would otherwise be impossible.

Completely unscrew and remove gear unit cover securing bolts -arrows-.

Pull cable reel from gear housing by hand in direction of arrow by tilting gently from side to side. Take care not to damage sealing surfaces.
The 3 damper elements in the recesses may drop out - take care not to lose them.

Pull dust and transportation cover from new motor in direction of arrow.
Ensure that flange seal and 3-winged retainer remain on gear housing.

Note:

Surfaces/components that are coated with grease must not be allowed to come into contact with dust or dirt. Only original grease G 000 450 02 should be used for regreasing.

Pull 3-winged retainer off gear shaft of new motor in direction of arrow. Leave rubber moulding in gear housing.
Check transmission components (rubber moulding, damping element) for damage, replace if necessary.

Insert 3-winged retainer in cable reel.

Note:

The 3 damping element must fit exactly into the cable reel recesses.

Attach window lifter motor to cable reel in direction of arrow.
The 4 lugs of the 3-winged retainer must coincide with the recesses in the rubber moulding in the gear housing.

Note:

If applicable, coat flange seal -a- and gear wheel in gear housing with a thin film of grease to stop them falling out.

If gear housing cannot be properly attached to cable reel, shift driver -arrow- slightly to alter position of rubber moulding so that it engages.

Note:

Never turn adjusting screw for top stop.

Screw in securing bolts and tighten to 3 Nm in the order shown.

Unscrew bonded rubber bushes -arrows- from defective window lifter motor.
Replace defective bonded rubber bushes.
Fit bonded rubber bushes in new window lifter motor and tighten to 3 Nm.
Test operation before installing in door component carrier.
To avoid scratching noise during operation, cut off protruding ends of subsequently attached cable ties.
