Determine starting torque of steering

First turn steering toward right in direction of travel until it stops.

Now turn steering uniformly toward left until it stops on friction meter, e.g. VAS 6222. Read off steering torque while doing this.

Specified value: 3 +/- 2 Nm

1 - Friction meter, e.g. VAS 6222

2 - 24 mm socket

If steering torque is exceeded

Loosen hydraulic thrust piece adjusting screws about one graduation line (turn adjustment screws toward left).

Then, check steering torque. Refer to Determine starting torque of steering .

If steering torque falls short

Install hydraulic thrust piece adjusting screws about one graduation line (turn adjustment screws toward right).

Then, check steering torque. Refer to Determine starting torque of steering .

Install steering gear. Refer to STEERING GEAR .

Perform vehicle alignment WHEEL ALIGNMENT .

Perform basic setting for Steering Angle Sensor -G85- via VAS 5051B in "Guided Fault Finding".

Then perform basic setting of steering system via VAS 5051B in "Guided Fault Finding".

First turn steering toward right in direction of travel until it stops.

Now turn steering uniformly toward left until it stops on friction meter, e.g. VAS 6222. Read off steering torque while doing this.

Specified value: 3 +/- 2 Nm

1 - Friction meter, e.g. VAS 6222

2 - 24 mm socket

Loosen thrust piece adjusting screws on steering pinion side about one graduation line (turn adjustment screws toward left).

Then, check steering torque. Refer to DETERMINE STARTING TORQUE OF STEERING .

If steering torque falls short

Install thrust piece adjusting screws on steering pinion side about one graduation line (turn adjustment screws toward right).

Then, check steering torque. Refer to DETERMINE STARTING TORQUE OF STEERING .

Install steering gear. Refer to STEERING GEAR .

Perform vehicle alignment. Refer to WHEEL ALIGNMENT .

Perform basic setting for Steering Angle Sensor -G85- via VAS 5051B in "Guided Fault Finding".

Then perform basic setting of steering system via VAS 5051B in "Guided Fault Finding".

STEERING PINION WITH STEERING TORQUE SENSOR

Note. Currently it is not possible to perform this repair.

Special tools and workshop equipment required

  1. Holding fixture VW 313
  2. Thrust piece 3253/6 qty. 2
  3. Torque wrench V.A.G 1331
  4. Torque wrench V.A.G 1332
  5. Transmission support T10108
  6. Adapter T10304
  7. Vehicle Diagnosis, Testing and Information System VAS 5051B
  8. 2 bolts M10 x 60

Removing

Remove steering gear. Refer to STEERING GEAR .

Clean steering gear in area of steering pinion, screw plug and adjustment screw.

Tension steering gear using 2 bolts M10 x 80 as depicted in the illustration.

Remove thrust piece on steering pinion side. Refer to THRUST PIECE, STEERING PINION SIDE, REMOVING, INSTALLING AND ADJUSTING .

Turn steering gear with screw plug upward.

  1. Tie rods must be assembled.

Remove the screw plug -arrow- and clean thread.

Scheme 1

Scheme 1

Remove the hex nut -arrow- from steering pinion.

Scheme 2

Scheme 2

Note. Steering rack moves up to stop when this is done.

Turn steering gear with steering pinion upward.

Remove sensor wire. Refer to SENSOR WIRE .

Note. Sensor wire must be replaced. It is supplied in replacement part set.

Mark position of steering pinion on steering gear housing.

Now pull steering pinion with steering torque sensor out of steering gear housing. Secure spiral spring against twisting using e.g. adhesive tape.

Scheme 3

Scheme 3

Note. If corrosion, damage, wear-out or first signs of soiling on steering rack can be seen, complete steering gear must be replaced. If no grease film is visible on steering rack, steering gear must also be replaced completely.

Installing

Scheme 4

Scheme 4
CAUTIONWhile doing this, no grease must enter the sensor or its vicinity!

Coat bushing -arrow 1- and splines of steering pinion -arrow 2- with G 052 192 A1.

CAUTIONDo not use other grease under any circumstances.

The new steering pinion with Steering Torque Sensor -G269- has an anti-twist element -arrow-. This may only be removed after locking to sensor wire.

Scheme 5

Scheme 5

Only remove new steering pinion from packaging when it has been assembled.

CAUTIONPrevent contact with electrical components!

Observe general repair notes for this. Refer to GENERAL REPAIR INFORMATION .

Insert steering pinion into steering gear housing.

Rotate steering pinion until spiral spring with sensor wire -arrow- can be locked. While doing this, the marking applied during removal must align with steering gear housing.

Note. Sensor wire must be replaced. It is supplied in replacement part set.

Pull anti-twist element off the spiral spring.

Tighten steering pinion with a new hex nut -arrow-.

Steering rack moves up to stop when this is done.

Fill hollow space of screw plug with grease G 052 192 A1.

Apply LOCTITE5910 sealant all around onto thread of screw plug -arrow- and install screw plug.

Install sensor wire. Refer to SENSOR WIRE .

Turn steering into straight ahead position using T10304.

For this purpose, dimension -a- = 25.5 mm.

Install and adjust thrust piece on steering pinion side. Refer to THRUST PIECE, STEERING PINION SIDE, REMOVING, INSTALLING AND ADJUSTING .

Tightening specifications, refer to ELECTROMECHANICAL POWER STEERING GEAR .

Install steering gear. Refer to STEERING GEAR .

Perform vehicle alignment. Refer to WHEEL ALIGNMENT .

Perform basic setting for Steering Angle Sensor -G85- via VAS 5051B in "Guided Fault Finding".

Then perform basic setting of steering system via VAS 5051B in "Guided Fault Finding".
