Known issues by generation
The RS6 (C5) is renowned for its thrilling performance, but potential owners should be mindful of particular issues. The 4.2L twin-turbo V8 often faces timing chain and tensioner failures, necessitating engine-out service for replacement at 80-120k miles. Turbocharger wear is common in the K04 units, requiring attention as they age. The ZF 5HP24A automatic transmission can exhibit valve-body wear, and the Dynamic Ride Control (DRC) system may also require replacement over time. Regular preventive maintenance is essential to keep this performance icon in peak condition.
