Service
• Review the following scenarios to determine the correct repair for the vehicle.
• Use ETKA to verify the build date and PR code for the vehicle.
• Only one scenario can be applied to the vehicle.
Tip: Date formats in ETKA:
• >> 20.06.2011: Indicates vehicles built up to 6/20/2011 or June 20, 2011
• 20.06.2011 >>: Indicates vehicles built after 6/20/2011 or June 20, 2011

Scenario A
If the vehicle was built before June 20, 2011, with PR-1LJ (29.5MM discs) (Figure 2), and it has not previously

Scenario B
If the vehicle was built before June 20, 2011 but has PR-1ZT (30MM discs) (Figure 3), perform steps 2 and 4
only under “Repair Procedure”, below.
If PR-1ZT is present DO NOT INSTALL 8K0698998 and DO NOT use SVM 03A004.

2. Apply a thin coat of anti-seize (G 052560A2) lubricant to the guide pins
of the caliper carrier prior to installing the brake pads (Figure 5). Only
apply this lubricant to the section of the guide pins that will be contacted
by the brake pads.

code should only be performed for repairs listed in Scenario A.

4. Road test the vehicle to seat the breaks and to verify that the noise has been eliminated.
