Specialized Maintenance for the Allroad Generations
Audi A6 Allroad C5 (4BH) | 1998–2005
The original Allroad is a modern classic, but its bespoke systems require careful attention.
- Air Suspension Troubleshooting: The C5 is known for "sagging" air bags. Our online manual covers how to find leaks, replace air springs, and fix the J403 compressor relay.

Audi A6 Allroad 4G (C7) | 2011–2018
The 4G generation refined the Allroad formula with more power and advanced electronics.

FAQ: Allroad Maintenance Tips
