2005 Audi A6 1.9L Diesel · RL54 LLC

The vehicle is currently roadworthy following a clean pass on May 1, 2026 at 178,916 miles. However, the maintenance trend reveals a reactive rather than proactive approach to repairs. A failure occurred just two weeks prior at 178,518 miles due to split outer drive shaft constant velocity boots and a failed rear fog lamp. While these issues were rectified quickly, the pattern of repeated failures suggests the owner only addresses mechanical faults when necessitated by annual testing rather than during routine servicing. The mileage profile is consistent with the vehicle's age, averaging approximately 8,500 miles per year over its 21-year life. This aligns with typical usage patterns for an older executive saloon. The data shows steady use, with roughly 12,000 miles covered between May 2024 and May 2025, and another 11,600 miles in the year leading up to the 2026 test. This regularity suggests the car is used regularly, which generally helps prevent components from seizing due to long periods of standing. A buyer must focus their physical inspection on the drivetrain and suspension components. The history shows multiple failures related to constant velocity boots, specifically both inner and outer joints across the 2025 and 2026 tests. You should check for grease leakage around the drivesfts and clicking noises during tight turns which would indicate joint wear. The 2025 advisory regarding reduced damping in both rear shock absorbers indicates these were replaced, but you should verify there are no new leaks from the units. The persistent non-excessive oil leak noted in 2025 warrants a close look at the engine block and sump housing to ensure the leak has not worsened into a critical failure. Given the 2024 report of pitted front brake discs, verify the current thickness and condition of the rotors and pads. Because this is a high-age vehicle, a thorough check of the subframe for structural corrosion is essential, as the record does not explicitly detail structural integrity concerns.
