Example of vehicle data sticker

At the start of MY 98, PR numbers were introduced to facilitate running gear/spring/shock absorber assignment.

‒ - A - indicates PR no. for front axle
‒ - B - indicates PR no. for rear axle
The running gear version installed in the vehicle can be seen from the corresponding PR number on the vehicle data sticker.

‒ - Arrow - indicates PR no. for running gear versions
In this example, the vehicle is fitted with standard running gear 1BA
-arrow-.

The vehicle data sticker can be found in the spare wheel well at the rear of the vehicle and in the Service booklet.

1BA = Standard running gear

1BB = Heavy-duty running gear (approx. 20 mm higher)

1BC = Special-purpose vehicles

1BD =Sports running gear (Audi S4)

RS4 = Sports running gear (RS4)

1BE = Sports running gear

1BV = Sports running gear (quattro GmbH)

1BQ = Sports running gear (South Africa)

1BT = Heavy-duty running gear (approx. 7 mm higher)

1BP = Heavy-duty running gear (trim position as for 1BA, however with limited bump travel)

Vehicles with special running gear -1BC- have the same wheel alignment specifications as the standard running gear -1BA-.

● Sensors properly attached and adjusted; heed manufacturer's operating instructions
● Tread depth on one axle must not differ by more than 2 mm
● Specified tyre inflation pressure
● When performing wheel alignment, make sure neither sliding base nor turntable is on end stop
● Vehicle kerb weight 1)
1) Kerb weight refers to weight of vehicle ready for operation (fuel tank and windscreen/headlight washer system fluid reservoir full, spare wheel, vehicle tool kit, jack) without driver.

Spare wheel, vehicle tool kit and jack must be in their specified positions.

● Vehicle properly aligned, bounced several times and allowed to settle
● Check suspension, steering and steering linkage for impermissible play and damage and service if necessary
● Perform wheel runout compensation
The permissible wheel runout may already cause the toe-in tolerance to be exceeded. The toe-in can then not be set correctly without performing wheel runout compensation.
Wheel alignment must be performed:

In the event of running problems

Following accident damage

If axle components have been removed

If one-sided tyre wear is found

ill add data its a long process

◆V.A.G 1907 Screw for steering centring
◆V.A.G 1925 Spacer gauge
◆V.A.G 1925/3 Adapter

Wheel runout compensation
Compensation must be provided for lateral runout of rims. Otherwise measurement result will be biased.
The toe-in cannot be set correctly without performing wheel runout compensation.

‒Perform wheel runout compensation. [/ul]

Heed appropriate instructions of wheel alignment equipment manufacturer when doing so. [/ul]










‒→ Insert brake pedal depressor V.A.G 1869/2. [/ul]
Crash vehicles
Screw for steering centring V.A.G 1907 must be inserted when performing wheel alignment on such vehicles.
Otherwise centre position of rack is not guaranteed.
Screw for steering centring V.A.G 1907 is only to be hand-tightened
