Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Air suspension compressor failure Vehicles with the optional air suspension (AAS) frequently suffer compressor failures that can cause the car to sink completely. Typical from 100,000 km. Symptoms: Car sinks on one side or completely, 'Suspension system fault' warning, compressor runs continuously from 100,000 km | High | |
| DRC suspension control valves rattle and leak The DRC hydraulic suspension on the RS6 C6 is highly problematic: control valves rattle audibly and dampers develop leaks. The 15 bar hydraulic system requires dealer-level special tooling for repairs. Symptoms: Rattling from the suspension especially over bumps, oil marks under the vehicle, unsettled handling from 70,000 km | High | |
| Control arms worn by high vehicle weight The vehicle weight of up to two tonnes leads to increased wear across the entire wheel suspension. Control arms are typically the first components that need replacing. Symptoms: Knocking over bumps, poor cornering behaviour, steering shimmy at higher speeds from 120,000 km | High | |
| Front control arms wear prematurely The high vehicle weight of the RS6 C6 causes above-average wear of front control arm bushings. Typical problem resulting from heavy weight combined with spirited driving. Symptoms: Knocking from the front axle, audible bushing wear, uneven tyre wear from 80,000 km | Medium |
