2018 Audi A6 2.0L Diesel · LG68 DZU

A dangerous front‑brake pad wear event recorded in July 2021 is the only major safety failure in the MOT history; the car has logged clean passes in every subsequent test, suggesting that the brake service required at that time was carried out and no further defects have been noted. Minor advisories for rear‑pad wear, a small chip in the drive‑zone, low‑level emissions reading and a windscreen blemish have appeared, but none have escalated to a failure, and the most recent MOT in June 2025 recorded no defects at all. At 144,781 mi over eight years the vehicle averages roughly 18,000 mi per annum, a mileage level that exceeds typical UK usage and points to accelerated wear on consumable items such as brake pads, tyres, suspension components and engine accessories. The MOT record shows no gaps in testing, so the high mileage is reflected consistently across the service life rather than being the result of a short period of intensive use. Consequently, wear‑related parts are likely approaching the latter stages of their service intervals and may require closer scrutiny during a pre‑purchase examination. When inspecting the car, give the braking system particular attention: confirm that front and rear pad thickness is comfortably above the legal limit, feel for any pedal sponginess, pulsation or grinding noise that could indicate worn discs or uneven pad wear, and listen for any squeal that might reveal glazed pads or calliper binding. Examine the windscreen for crack propagation from the previously noted damage, checking especially the driver’s line of sight and the integrity of the surrounding seal. The 2022 advisory about a low emissions reading warrants a functional check of the exhaust after‑treatment system – look for excessive smoke, unusual exhaust tones or fault codes that could signal a failing oxygen sensor or DPF issue. Finally, inspect the under‑tray area for corrosion or damage, as this region can be vulnerable on high‑mileage, heavily used vehicles and may affect structural integrity or lead to future rust problems. A thorough pre‑purchase inspection by a qualified mechanic is advisable, focusing on brake pad and disc condition, windscreen integrity, emissions system performance and under‑tray corrosion. Given the mileage, also request a check of suspension bushings, ball joints and tyre tread depth for signs of fatigue or uneven wear, and verify that any recent brake or emission‑related work is documented. Addressing these points will clarify whether the vehicle’s current state aligns with the buyer’s expectations for reliability and safety.
