Volkswagen Golf / Golf Plus. Manual - part 75

 

 

Caution

The assembly head -1- must never be within area -a- of tyre

valve/tyre pressure sensor, or the assembly head will damage

the tyre pressure sensor .

– Position assembly head -1- near tyre valve/ tyre pressure sen‐

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

to the tyre valve/ tyre pressure sensor -2-.

– Seat depressor -3- on wheel rim opposite assembly head

-1-.

– 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.

This action will push the depressor -1- up against the assembly

head. This allows it to be removed easily.

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

sensor -2- is directly in front of assembly head -1-.

Caution

The assembly head -1- must never be within area -a- of tyre

valve/tyre pressure sensor, or the assembly head will damage

the tyre pressure sensor .

– Position assembly head -1- near tyre valve/ tyre pressure sen‐

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

to the tyre valve/ tyre pressure sensor -2-.

– Now lever tyre bead over assembly finger on assembly head

using assembly lever -3-.

– Additionally insert a plastic assembly lever -4-.
– Remove assembly lever -3-.

tyre is pulled completely off wheel rim.

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

Fitting tyre to wheel rim

Caution

♦ Follow the instructions for warming cold tyres to minimum

installation temperature 

⇒ page 294

♦ Follow the notes on safety 

⇒ page 294

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

bead generously with tyre assembly paste.

– Turn wheel rim on tyre fitting unit so that tyre valve/ tyre pres‐

sure sensor -1- is directly opposite assembly head -2-.

– Run tyre fitting machine clockwise.

– Stop the fitting of lower bead before reaching tyre valve/ tyre

pressure sensor -arrow- to prevent damage to tyre pressure

sensor .

The tyre bead will now slide over the wheel rim flange. The wheel

rim may only be turned until the assembly head is just before the

tyre valve/ tyre pressure sensor -arrow-.

– Fit depressor -3- on wheel rim.
– Check to ensure that tyre bead is seated correctly on assembly

head and run tyre fitting machine clockwise.

– Stop the fitting of upper bead before reaching tyre valve/ tyre

pressure sensor -arrow- to prevent damage to tyre pressure

sensor .

The tyre bead will now slide over the wheel rim flange. The wheel

rim may only be turned until the assembly head is just before the

tyre valve/ tyre pressure sensor -arrow-.
– Remove depressor from wheel rim.
– Inflate tyre to a pressure of max. 3.3 bar (bead seating pres‐

sure)

Caution

Never increase the inflation pressure when the tyre bead does

not lie completely against the wheel rim flange.
This would lead to damage to the tyre and/or the wheel rim.

– When the tyre bead does not lie completely against the wheel

rim flange: deflate the tyre, press tyre bead off wheel rim flange

and generously coat again with tyre assembly paste.

– Inflate tyre to a pressure of max. 3.3 bar (bead seating pres‐

sure)

– If the tyre beads seat perfectly against the shoulder of the

wheel rim, increase pressure to 4 bar to “seat” the tyre.

– Fit a new nickel-plated valve insert and inflate tyre to prescri‐

bed inflation pressure.

– Then balance wheel.
– Install wheel and tighten bolts to specified torque

General notes:
The tyre pressure monitor system is part of the software in the

ABS control unit -J104- . The system is used to detect slow tyre

pressure loss from a wheel. Fault memory entries for the tyre

monitor display are stored in the ABS control unit -J104- . The tyre

pressure display compares the wheel speeds and consequently

the rolling circumference of the individual wheels via the ABS

sensors.
After the following work or modifications, the tyre pressure mon‐

itor display button -E492- must be pressed and held until a

confirmation is sounded.
♦ Change in tyre pressure
♦ Changing one or more wheels
♦ Interchanging wheels, e.g. from front to rear
A change in the wheel's rolling circumference will be indicated by

the TPM warning lamp -K220- lighting up in the instrument cluster.

A tyre's rolling circumference may change as a result of:
♦ Insufficient tyre inflation pressure.
♦ Structural tyre damage.
♦ One-sided loading of vehicle.
♦ Increased load on one axle, e.g. due to towing a trailer.
♦ Use of snow chains.
♦ Spare wheel installed.
♦ Wheel renewal.
System fault in the ABS system.
If a fault in the ABS is displayed by the ESP and TCS warning

lamp -K155- or the traction control system warning lamp -K86- ,

then the tyre pressure monitor warning lamp -K220- -arrow- will

also light up. However, no fault will be stored in the system for the

tyre monitor display.
The warning lamp cannot be extinguished by pressing the TPM

button -E492- . In this case, please carry out the following steps:
– Connect vehicle diagnosis, testing and information system -

VAS 5051- and select “Guided fault finding” ⇒ Vehicle diag‐

nosis, testing and information system VAS 5051.
