Known issues by generation
For the B9 RS4 Avant, notable concerns include carbon buildup on the intake valves due to its EA839 twin-turbo V6, requiring periodic walnut blasting for maintenance, typically between 60,000-80,000 miles. Additionally, the high-pressure fuel pump (HPFP) can wear down, especially in tuned vehicles. The 8-speed Tiptronic is generally robust; however, valve-body wear may occur in high-mileage examples. The sport differential and dynamic damping system are critical for performance, with pre-failure costs ranging from $2,000 to $6,000, depending on the issue. Collectors should ensure these aspects are carefully monitored during ownership.

The value of a B9 RS4 Avant is significantly influenced by its condition and history. Examples in original paint, particularly in exclusive colors like Nardo Gray and Sonoma Green, command a premium in the collector market. The ironclad wagon premium over sedans is evident, with auction results on Bring a Trailer and Cars & Bids illustrating that wagons routinely fetch $70,000 to $110,000, while sedan counterparts fall short.
