01772 on Audi by Model
Audi S6(1 issue)
- 2013 Audi S6 Air-Suspension Compressor or Relay Fault - Diagnosis Required2013
Audi TSB 2018765/8 covers 2013 C7 S6 vehicles with air suspension when ride-height adjustment is unavailable, the compressor continues running after shutdown and locking, or the system lowers the car and displays a warning. The bulletin identifies a compressor or J403 relay diagnostic path; it does not establish a universal leaking-strut or valve-block defect.
Audi SQ7(1 issue)
- Adaptive Air Suspension Compressor and Air Spring Failures2020-2024
The Audi SQ7's sport-calibrated adaptive air suspension system (4M chassis, shared with Q8/SQ8/Bentley Bentayga/Lamborghini Urus) develops failures in air springs, the compressor, valve block, and height sensors. Compressors typically last 80,000-100,000 km but high ambient temperatures, frequent off-road use, or air leaks cause premature failure. Air spring leaks cause the compressor to run continuously (even with engine off), eventually burning it out. The SQ7's significant curb weight (5,500+ lbs) stresses the system more than lighter vehicles on the same platform.
