listed in this TSB, perform steps 1 – 4 under “Repair Procedure”, below.

Figure 2. ETKA screen shot for vehicles built up to June 20, 2011 with PR 1LA.

Scenario B
If the vehicle was built before June 20, 2011 with PR-1LA but now has PR-1ZB (Figure 3), this TSB does not apply
since it has already been performed.
If PR-1ZB is present DO NOT INSTALL 8R0698998A and DO NOT use SVM 03A004.

Repair Procedure
Only perform the necessary steps listed under the applicable scenario above. All of the following steps may not be
required.
1. Install parts kit with part number 8R0698998A. The kit includes the following components:
• 1 set of brake pads with wear indicator for disc brakes
• 2 front brake discs
• 2 brake carriers
• 4 hexagonal collar bolts
• 2 hexagonal countersunk screws
See Elsa >> Repair Manual >> Chassis >> 46 Mechanical Components >> Removal and Installation >> Front
Brakes, FBC-57 >> Front Brake Pads, FBC-57.
Tip: Brake pads must be securely glued to the calipers.
2. Apply a thin coat of anti-seize lubricant (G 052560A2) to the guide pins of
the caliper carrier prior to installing the brake pads (Figure 5). Only apply
the lubricant to the section of the guide pins that will be contacted by the
brake pads.

Figure 5. Caliper carrier guide pins
with anti-seize lubricant applied
where the pads make contact.
3. Follow all instructions in TSB 2011732, 00 Software Management (SVM), operating instructions, to update the
vehicle’s front brake PR code data using the SVM action code listed in the table below. Use Audi Flashing >>

Tip: The change is necessary to ensure correct parts are installed during future brake service. This SVM 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.

Tip: If the vehicle still exhibits brake noise after all of the repairs stated above have been accurately
performed:
• Obtain a sound recording, create a TAC ticket, and attach the sound recording.
• Do not open a TAC ticket without a sound recording.
