Volkswagen Golf / Golf Plus. Manual - part 73

 

 

3.1

General information

Since model year 2005, new wheel rims with a modified contour

have been used in all vehicles.
The tyre fitting unit must be fitted with the tyre fitting head de‐

signed for these wheels.

WARNING

Otherwise there is a danger that the wheel will be damaged.

If the tyre fitting unit has not been modified, please contact the

manufacture of the unit.

with tyre pressure monitoring)

Notes on safety and conditions for re‐

moving and fitting tyres (wheels with tyre

pressure monitoring)

• It is extremely important to adhere to the instructions and

warnings in the following descriptions.

• Check whether the tyre pressure sensor should also be re‐

placed ⇒ Vehicle diagnosis, testing and information system

VAS 5051.

Note

Ensure that the tyre does not contact the tyre pressure sensor

during removal or fitting.

The tyre pressure sensor must not come into contact with wa‐

ter or be blown upon with compressed air when the wheel rim

is cleaned.

4.2

Wheel change

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 vehi‐

cle speed. This process takes approx. 7 minutes.
The tyre pressure monitor control unit -J502- must first switch to

learning mode before it can automatically learn the wheel elec‐

tronics.
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 con‐

sequently 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 Volkswagen-approved

wheel and tyre combinations with the tyre inflation pressure

specified in the tank flap may be installed.

If unapproved wheel and tyre combinations are installed, they

must possess a certificate from the responsible technical in‐

spection authority (in Germany, TÜV) for the respective vehi‐

cle, and a second wheel set must be learned via the Vehicle

diagnosis, testing and information system -VAS 5051B-

⇒ page 291

 .

Learning is also necessary if the tyre inflation pressure devi‐

ates from the tyre inflation pressure specified in the tank flap

⇒ page 291

 .

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 diagnosis, testing and

information system -VAS 5051B- .
The wheel electronics for the wheels of the second wheel set are

not automatically detected and learned by the TPM system (unlike

the wheel electronics for the wheel set with Volkswagen-ap‐

proved wheel and tyre combinations).
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.

Pressing tyre off wheel rim

Caution

♦ Comply with the notes on safety and conditions

⇒ page 290

– Deflate tyre by unscrewing nickel-plated valve insert.
– When pressing off a tyre using tyre fitting equipment with a

press-off plate, always ensure that the tyre valve/ tyre pres‐

sure sensor -arrow- is directly opposite the bead breaker -1-.

The bead breaker must be positioned no more than 2 cm from

wheel rim flange.
– Remove balance weights and excessive dirt from wheel.

– Press both tyre beads off all round and liberally coat tyre and

wheel rim flange with tyre assembly paste -arrow-.

4. Removing and fitting tyres (wheels with tyre pressure monitoring)    

291

 

Caution

♦ Comply with the notes on safety and conditions

⇒ page 290

♦ The assembly head must never be within area -a- of tyre

valve/tyre pressure sensor, or the assembly head will

damage the tyre pressure sensor .

Fitting tyre
– Turn wheel on tyre fitting unit so that tyre valve/ tyre pressure

sensor is in front of the assembly head.

– Position assembly head near tyre valve/ tyre pressure sensor

so that an assembly lever can be inserted approx. 30° next to

the tyre valve/ tyre pressure sensor .

– Now lever tyre bead over assembly finger on assembly head

using assembly lever then remove assembly lever.

– Run tyre fitting machine clockwise until upper bead lies com‐

pletely above wheel rim flange.

– Turn wheel on tyre fitting unit so that tyre valve/ tyre pressure

sensor is in front of the assembly head.

Note

Check that the tyre pressure sensor is not loose or damaged.

If the screwed connection is loose, replace the union nut, the

valve insert, the seal, the sealing washer and the valve cap

with new parts from the repair set ⇒  Electronic parts catalogue

“ETKA” .

If the tyre pressure sensor is damaged, then replace the com‐

plete item 

⇒ page 304

 .

4.5

Fitting tyre to wheel rim

Caution

♦ Comply with the notes on safety and conditions

⇒ page 290

Note

When a tyre is changed, it is recommended also to change the

set of seals for the tyre pressure sensor.

– Coat wheel rim flanges, tyre beads and inside of upper tyre

bead generously with tyre assembly paste.

– First fit inner side of tyre.
