Known issues by generation
For the RS6 C5, a notable concern is the timing chain and tensioner on the 4.2L twin-turbo V8, which requires engine-out service for replacement. Turbocharger wear, especially on the K04 units, can lead to costly rebuilds. The Dynamic Ride Control (DRC) system may also require attention, along with the strong but high-mileage wear of the ZF 5HP24A transmission's valve body. Preventive maintenance is key for preserving the value of this performance car, which is why service records are invaluable for collectors.
