Product Details

This part number, 03291, is the correct reference to use when matching the rear coil spring to the confirmed Audi A6 and Audi S6 applications.

Common Reasons for Replacement

• Sagging rear ride height
• Broken or weakened rear spring

Installation Notes

Verify the OE number 4F0511115BT and the paint-mark combination before ordering. Confirm the rear position and VIN break for 2011 Audi A6 Quattro and 2011 Audi S6 applications. Replace springs in matched pairs when the opposite side shows similar wear, and inspect related rear suspension components during service. Part number 03291 should be matched to the exact rear spring specification shown in the fitment data.
