General

Wheel alignment must always be checked with VW/Audi-ap‐

proved wheel alignment equipment.
Whenever wheels are aligned, both the front and rear axles must

be measured.
Otherwise, the steering rack may not be centred!
– Perform all measurements with wheel alignment computer.
All the information required to perform alignment can be found in

the wheel alignment computer.
Current data “updates” are located on VW Service Net.

Note

Wheel alignment should not be checked before the vehicle has

completed 1,000 to 2,000 km because the coil springs must

settle.

When making adjustments, adhere to the relevant specifica‐

tions as closely as possible.

Wheel alignment is necessary if:
♦ The vehicle does not handle properly.
♦ Vehicle has been involved in an accident and components

have been renewed.

♦ Axle components are removed or renewed.
♦ Tyres are worn unevenly.
Components have been renewed.

Test prerequisites

• Check suspension, wheel bearing, steering and steering link‐

age for excessive play and damage.

• Tread depth difference of no more than 2 mm on one axle.
• Tyres inflated to correct pressure.
• Vehicle unladen.
• Fuel tank must be full.
• Spare wheel and vehicle tools are stowed in correct locations.
• The fluid reservoir for the windscreen/headlight washer sys‐

tem must be full.

• When checking wheel alignment, ensure that sliding plates

and turn tables are not touching end stop.

Please note!
• The test equipment must be properly adjusted and attached

to the vehicle; observe device manufacturer's operating in‐

structions.

If necessary, contact the manufacturer for familiarisation with the

proper use of the wheel alignment equipment.
Wheel alignment platforms and wheel alignment units and com‐

puters can lose their calibration over a period of time.
Wheel alignment platforms and alignment units and computers

should be checked and adjusted as necessary during inspection

and maintenance at least once per year!
– Treat these highly sensitive units carefully and conscientious‐

ly!

8.3

Test preparations

Special tools and workshop equipment required
♦ Brake pedal actuator -V.A.G 1869/2-

The existing lateral runout of the wheel must be compensated for.

Otherwise, the result of the measurement will be incorrect.
If runout compensation is not performed, it is not possible to adjust

toe-in correctly!
Observe information provided by the manufacturer of the wheel

alignment unit.
– Carry out wheel run-out compensation.
