On the 2009-2025 Audi A4 Avant, rear upper shock mount bushings wear out, causing a knocking noise from the rear when going over bumps. The Avant's heavier rear end accelerates bushing wear compared to the sedan. Common after 60,000 miles.
Common Symptoms
- Knocking from rear over bumps
- Rear-end looseness
- Uneven rear tire wear
- Popping noise from trunk area
How to Fix
Replace rear upper shock mount bushings. Consider replacing rear shocks at the same time if over 80,000 miles. Bilstein B4 or Sachs OE replacements are recommended. Realign rear suspension after service.

On the 2009-2025 Audi A4 Avant, the retractable cargo cover latch mechanisms on either side break, preventing the cover from staying attached to the D-pillars. The internal spring that retracts the cover also weakens or breaks, leaving the cover hanging loose.
Common Symptoms
- Cargo cover won't stay latched
- Cover hangs loose
- Cover won't retract
- Rattling from cargo area
How to Fix
Replace broken latch clips (available individually from Audi parts). If the retract spring is broken, the entire cargo cover cassette must be replaced. Aftermarket covers are available at lower cost than OEM.
