2018 Audi A3 1.5L Petrol · ML18 WVC

A consistent pattern of rear axle wear has emerged across the MOT history of this 2018 Audi A3, with brake discs and tyres on the back of the vehicle appearing repeatedly over multiple test cycles. The most recent assessment on 16 March 2026 recorded a pass alongside an advisory for a nail in the nearside rear tyre and another noting that the nearside rear brake disc was worn, pitted or scored but not seriously weakened. This continues a theme visible from as far back as 2022, when the nearside rear brake disc was first flagged with the same condition, and rear tyre perishing was noted on both sides. The intervening tests in 2023 and 2025 continued to highlight rear tyre deterioration, while 2021 and 2024 passed without recorded defects. There are no failures on the record, but the recurrence of similar advisories at the rear wheels points to a mechanical narrative centred on those components rather than a uniformly clean roadworthiness history. With a recorded mileage of 65,489 miles across roughly eight years, this A3 has averaged around 8,186 miles annually, which sits broadly in line with typical usage for a vehicle of its age. The MOT testing has been carried out consistently each year without any gaps, suggesting the car has remained in regular use rather than being laid up for extended periods. The mileage progression between tests appears steady, with no abrupt jumps that would indicate prolonged off-road storage followed by heavy use. This kind of consistent annual accumulation tends to keep consumables and suspension components working within normal wear parameters, although the specific advisories recorded suggest that the rear axle in particular has been subjected to wear patterns worth scrutinising on inspection. A prospective buyer should pay particular attention to the rear braking system, given that the nearside rear disc has now been flagged with pitting and scoring at two separate MOT tests four years apart. On a test drive, listen for any grinding or rubbing noises from the rear wheels when moving off from a standstill, as binding calipers often accompany worn rear discs on this generation of A3. The pedal feel should be firm and progressive without excessive travel, and the vehicle should pull up straight without any rear bias or pulling to one side under heavy braking. The handbrake should hold the car securely on an incline, as rear brake issues can sometimes manifest as poor handbrake performance. Visually, inspect the rear discs through the wheel spokes for a pronounced lip at the outer edge and any blueing from overheating, both of which would suggest the discs have worn beyond the advisory threshold. The rear tyres also warrant close examination, given the recurring advisories for perishing, cracking and wear close to the legal limit across consecutive tests. Check the sidewalls and tread blocks carefully for any signs of cracking, particularly in the grooves between the tread ribs, as this can indicate age-related rubber degradation independent of tread depth. Uneven shoulder wear on the rear tyres may suggest alignment issues at the rear axle, which is worth investigating. During the test drive, pay attention to any steering vagueness or instability at speed, as worn rear tyres combined with any rear suspension wear can produce a nervous or unsettled feeling through corners. A steady, even wear pattern across all four corners would be reassuring, but given the documented history, the rear axle components should form the main focus of any pre-purchase evaluation.
