In South Carolina, the Audi RS4 Avant (B9), produced from 2018 onwards, stands as a beacon for automobile enthusiasts. This iconic wagon combines luxury with performance, featuring a 2.9L EA839 twin-turbo V6 engine that delivers 444hp and 442 lb-ft of torque. Despite its automatic transmission, the RS4 Avant’s quattro all-wheel drive and sport differential offer an exhilarating driving experience, making it a sought-after model among collectors. Unlike its predecessor, this generation has become a grey-market gem, and any US-titled example is a rare find, especially in its stunning original colors like Nardo Gray and Misano Red Pearl.
As the wagon-niche-enthusiast-collector pipeline continues to grow, the B9 RS4 Avant captures a dedicated following, despite some purists lamenting the loss of the naturally aspirated V8. Enthusiasts respect preventive maintenance, especially regarding carbon buildup and high-pressure fuel pump concerns. By donating your RS4 Avant, you contribute to an ever-appreciating market that celebrates this unique wagon’s legacy, ensuring it finds a new home among passionate collectors.

Known issues by generation
For the B9 RS4 Avant, notable issues include carbon buildup in the 2.9L EA839 twin-turbo V6, which necessitates regular walnut blasting to maintain performance. Additionally, the high-pressure fuel pump can exhibit wear in tuned examples, and careful attention needs to be paid to the 8-speed Tiptronic's mechatronic units at higher mileages. The sport differential and dynamic damping systems are known for potential pre-failure, leading to costly repairs if not addressed. While these concerns exist, they do not overshadow the model’s appeal, especially with proper preventive maintenance.
