2014 Audi A6 2.0L Diesel · BT64 HLC

Recurring suspension and drivetrain component failures define the mechanical history of this Audi A6, with several major defects recorded between 2023 and 2024. The vehicle has experienced multiple failures involving fractured coil springs, deteriorated constant velocity boots, and ball joint dust cover issues, alongside a dangerous failure for an exposed tyre cord in July 2023. While the most recent test on 04 July 2025 resulted in a pass with no defects recorded, the preceding years show a pattern of significant component wear and immediate remedial action required to maintain roadworthiness. The recorded mileage of 117,010 miles over approximately twelve years equates to an average annual usage of roughly 9,751 miles. This represents a typical usage pattern for a vehicle of this age and class, suggesting consistent rather than excessive road use. Mechanically, this level of accumulation means that components such as suspension bushes, coil springs, and drive shaft joints are reaching the end of their typical service life, which is consistent with the specific failures documented in the MOT history. Prospective buyers should pay close attention to the rear braking system and suspension integrity. An advisory for a fluctuating nearside rear service brake was noted in August 2024, which persisted into the following year. During a test drive, listen for any rhythmic clicking or grinding from the rear, and feel for any pulsation or unevenness through the brake pedal when applying pressure. Given the previous failures of both nearside front and rear coil springs, it is essential to inspect the suspension for any signs of sagging or uneven ride height and to listen for knocking or clunking noises when driving over uneven surfaces or speed bumps, which could indicate worn suspension bushes or damaged spring seats. The history of drive shaft and CV boot deterioration also warrants a close inspection of the front drivetrain. The records show a progression from an insecure inner clip in 2023 to a severely deteriorated outer CV boot in 2024. On a test drive, pay particular attention to any clicking sounds when turning the steering wheel to full lock, which can be a symptom of a failing constant velocity joint. Additionally, check the area around the nearside front drive shaft for any signs of grease spray, which would indicate a split boot and potential ingress of contaminants into the joint.
