2004 Audi A6 1.9L Diesel · SH54 FKC

The vehicle passed its most recent MOT on 25 September 2025, though the overall maintenance trend suggests a vehicle entering a phase of accelerating wear. The failure in September 2025 involving an SRS warning lamp and a split CV boot, combined with recurring advisories for braking components and steering joints, indicates a reactive rather than proactive approach to maintenance. While the vehicle is currently roadworthy, the frequency of major failures and the persistence of advisories suggest that critical wear and tear items are being addressed only when they reach the point of failure. With a recorded mileage of 247,970 miles over 22 years, the vehicle has averaged approximately 11,271 miles per year. This usage is typical for a long distance cruiser of this era, but the sheer volume of mileage places significant stress on the drivetrain, suspension bushes, and engine internals. At nearly a quarter of a million miles, the mechanical components are well beyond their primary design life, meaning the buyer should expect a higher frequency of component failure and a greater need for comprehensive overhaul of the chassis and powertrain. The MOT history reveals a systemic issue with the braking system, with all four brake discs currently flagged as worn, pitted, or scored. A prospective buyer should listen for rhythmic pulsations through the brake pedal or a grinding noise during deceleration, which indicates surface irregularity on the discs. Furthermore, the recurring advisory for the nearside front track rod end suggests imminent steering play. During a test drive, pay close attention to any vagueness in the steering feel or a knocking sound when turning the wheel at low speeds. The previous records of corroded brake pipes and deteriorated hoses also necessitate a thorough visual inspection of all hydraulic lines for signs of bulging or further oxidation. The history of split constant velocity boots on both the inner and outer drive shafts indicates a vulnerability in the drivetrain. Ensure there are no clicking sounds during tight, low speed manoeuvres, as this would suggest the CV joints have been contaminated by road grit and are now failing. Additionally, the previous SRS warning lamp failure is a point of concern; verify that no airbag or seatbelt warning lights remain illuminated on the dashboard, as these are critical safety systems. Given the extreme mileage, the buyer must also verify the service history for timing belt and water pump replacements, as these are critical failure points for this engine architecture.
