2015 Audi A6 2.0L Diesel · MM15 JUX

A rear‑suspension failure looms as the pivotal event in this car’s MOT record – the 2021 test flagged a fractured nearside rear coil spring and sub‑minimum tread on both rear tyres, both classified as dangerous. The subsequent three-year streak of clean passes (2022‑2025) indicates that the spring and tyre issues were remedied, and no further defects have been recorded, suggesting the vehicle has been roadworthy since that repair. At 294,035 mi for an eleven‑year‑old Audi A6 the annual average of roughly 26,700 mi is well above the typical UK usage pattern. Such mileage accelerates wear on consumables and load‑bearing components; it also raises the likelihood of fatigue in suspension bushings, engine mounts, and drivetrain bearings. The MOT history shows no gaps, but the high mileage combined with the earlier rear‑spring fracture points to a vehicle that has been heavily employed and therefore may be approaching the end of service life for several wear items. When inspecting the car, give particular attention to the rear suspension assembly. Listen for clunking or knocking over bumps, feel for any sag or asymmetry when the rear is compressed, and verify that the coil springs are intact and securely mounted. Examine all four tyres for tread depth, uniform wear patterns and sidewall condition; uneven wear could hint at lingering alignment or suspension issues. Check the brake system for any pulsation in the pedal, excessive rotor run‑out, or uneven pad wear, especially given the high mileage and the earlier tyre wear that may have masked braking performance. A comprehensive pre‑purchase examination by a qualified technician is essential. Request confirmation that the rear coil spring was replaced with an OEM‑spec part and that the tyres were renewed to a full set. Have the inspector assess suspension bushings, ball joints, and subframe integrity for corrosion or fatigue, and inspect the engine and transmission for oil leaks, excessive play, or abnormal noises. A short test drive should include steady‑state cruising, hard braking, and cornering to reveal any steering pull, vibration, or pedal judder before committing to purchase.
