Volkswagen Golf Service & Repair Manual: Fitting wheel, fitting instructions for Volkswagen

Vehicles with tyre pressure sensor

If the wheels are changed (e.g. switch from summer to winter tyres), the wheel electronics transmit data as soon as the speed of the new wheels exceeds 25 km/h. The new wheel electronics' ID numbers are automatically detected and entered by the control unit. The acceleration data are additionally checked against the vehicle speed. This process takes approx. 7 minutes. The tyre pressure monitoring system control unit -J502- must first switch to learning mode before it can automatically learn the wheel electronics. To do this, the vehicle must remain stationary for 20 minutes. Following the detection of a flat tyre, this time is 5 minutes. If the stationary time is not maintained and the control unit consequently does not switch to learning mode, the system detects interference in transmission and will learn the wheel electronics automatically only after a stationary period of 20 minutes.

Note When changing wheels, note that only wheel and tyre combinations approved by the vehicle manufacturer with the tyre inflation pressure specified in the tank flap may be installed. If unapproved wheel and tyre combinations are installed, a certificate from the responsible technical inspection authority must be available for the respective vehicle, and a second wheel set must be adapted via the → Vehicle diagnostic tester. An adaptation is also necessary if the tyre pressure deviates from the tyre pressure specified on the tank flap.

Tyre sets with other specified tyre inflation pressures

If a vehicle is fitted with tyres requiring nominal tyre inflation pressures other than those specified on the tank flap sticker, these tyres (second wheel set) can also be monitored with the TPM system. Nominal tyre inflation pressures for the second wheel set must be specified to the system with the → Vehicle diagnostic tester. The wheel electronics for the wheels of the second wheel set are not automatically detected and adapted by the TPM system (unlike the wheel electronics for the wheel set with wheel and tyre combinations approved by the vehicle manufacturer).

The following work has to be performed to switch to the second wheel set:

Read ID numbers (IDs) of the wheel electronics (tyre pressure sensors) prior to installation.

Switch the TPM to wheel set 2.

Enter the necessary nominal tyre pressures and the IDs of the wheel electronics in the system.

Continuation for all vehicles

Note The width across flats of the provided wheel bolt adapter may differ from the width across flats of the adapter set.

Special tools and workshop equipment required

Fitting wheel, fitting instructions for Volkswagen

Adapter set for anti-theft wheel bolts -T10101 A-

Adapter set for anti-theft wheel bolts -T40004-

Adapter set for anti-theft wheel bolts -T40073-

Wax spray -D 322 000 A2-

Optimol TA paste -G 052 109 A2-

Switch off ignition.

WARNING Perform the checks and follow the instructions listed below. This is important to ensure that the wheel bolts and the wheels are properly secured.

Note On vehicles with tyre pressure indicator, the tyre pressure indicator has to be recalibrated any time one or more wheels are removed or fitted → Vehicle diagnostic tester.

Check to ensure that contact surfaces -arrows- on brake disc are free of corrosion and dirt.

Check to ensure that contact surface -arrow- on centring seat of brake disc are free of corrosion and dirt.

Check to ensure that contact surface -arrow- on inner side of wheel (rim) and also centring seat of rim are free of corrosion and dirt.
The concave seats ^* in the holes for the wheel bolts and the threads of the wheel bolts must also be free of corrosion and dirt, oil or grease.

^* The concave seat is the curved surface of a section of a sphere cut by a plane.

Check whether the wheel bolts can be easily screwed in by hand. The thread of the wheel bolts must not come into contact with the bore in the brake disc -arrow-.

If the thread of the wheel bolt touches the hole -arrow-, turn the brake disc relative to the wheel hub accordingly.

If necessary, remove dirt and corrosion:

Oil or grease from contact surfaces

Oil or grease from threads in wheel hub

Oil or grease from threads in wheel bolts

WARNING

Damaged, badly corroded or difficult to remove wheel bolts must be renewed.

Applies to alloy and steel wheels

When changing a wheel, wheel centring seat should be waxed using wax spray to prevent corrosion between wheel centring seat and wheel rim → Electronic Parts Catalogue “ETKA”.

Remove wheel.
Thoroughly clean wheel centring seat on wheel hub and the centring ring of the wheel rim.

Apply wax to centring area -arrow- with a brush.

Ensure that only centring ring -arrow- but not contact surface of wheel rim has been waxed. Otherwise, the brakes will be soiled, which would reduce the braking efficiency.

WARNING Wheel bolts, contact surfaces of wheel hub and wheel rim and wheel hub threads must not be waxed. Never treat wheel securing bolts with lubricant or corrosion protection materials!

1 -	When fitting the wheel, pull in all wheel bolts uniformly by hand.

2 -	Tighten wheel bolts in diagonal sequence to 30 N·m.

3 -	Lower vehicle onto floor. Use torque wrench to tighten wheel bolts diagonally to specified torque.

Do not use an impact screwdriver!
