4 Removing and fitting tyres (wheels
with tyre pressure monitoring)
4.1 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.

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 .
