Cracking or creaking noise from the clutch pedal/master cylinder area may be noticed when operating the clutch pedal on 2011 Audi A4, A5, S4 and S5 vehicles.
The cause may be the result of an incorrect component.
- Replace the mounting pin for the clutch master cylinder input rod with P/N WHT 001 666 according to the repair manual.
- Apply 1g of grease G 052 128A1 on the eye of the master cylinder. Also continuously grease the pin WHT 001 666 in the contact area between the pin and the master cylinder.
- Make sure that the pin is correctly attached and recheck for proper operation. The pin does not have to be secured by an expanding rivet, even if a rivet was incorrectly fitted by the factory. The clutch master cylinder is not the cause of the complaint. Do not replace the clutch master cylinder.
Note the mounting pin (No. 5 in illustration).
