2018 Audi A3 2.0L Petrol · DC18 CVR

Front brake wear has emerged as the defining mechanical theme of this 2018 Audi A3 in its later MOT history, with the most recent test on 10 April 2026 passing only after advisory notices were raised against both front brake discs (worn, pitted or scored nearside and offside) and the front brake pads (wearing thin nearside and offside). Prior to this, the vehicle carried a clean pass sheet from 2022 through 2024 with no advisories recorded, before tyre degradation became the focus in March 2025 when the offside front tyre was flagged for a cut alongside perishing and inner-edge wear, with the nearside front tyre also showing cracking. Earlier in 2021, all four tyres were simultaneously noted as worn close to the legal limit with edge wear at 3mm, suggesting a pattern of front-end geometry or alignment behaviour that has historically loaded the tyre shoulders. The overall trajectory is therefore one of a long stable period followed by a cluster of component-level advisories relating to braking and tyres in the final two tests, rather than any structural or lighting failures. Annual mileage of roughly 6,978 miles places this car near the average usage band for an eight-year-old vehicle, and the recorded odometer readings across the MOT history progress in broadly even increments consistent with steady mixed use rather than high motorway accumulation or extended periods off the road. There are no large unexplained gaps in the test record and no missing annual tests, which means there is no multi-year lay-up that would raise concerns about seized calipers, perished rubber, brake fluid degradation, or stale fuel. The mid-range mileage supports the likelihood that consumables such as brake pads, discs, and tyres have done moderate rather than severe duty, but it also means that age-related polymer deterioration is still in play on items like tyres, which the 2025 advisories confirm is happening regardless of how few miles have been covered. For a prospective buyer, the immediate priority is a physical inspection of the front braking system given the April 2026 advisories. The discs should be examined for lip measurement, surface pitting depth, and runout, as the advisory explicitly notes pitting that has not yet reached the seriously weakened threshold, meaning replacement is imminent if the car is to be kept for another twelve months. Pad material thickness should be measured with a depth gauge to confirm whether it has dropped below the typical 3mm warning band, and the caliper slide pins should be checked for seizing, since binding calipers are a common cause of uneven or accelerated pad wear on A3 platforms and would explain why both nearside and offside have worn at similar rates. On test drive, listen for any scraping or metallic squeal from cold starts and feel for judder through the steering wheel or brake pedal under firm braking, which would indicate disc runout beyond service tolerance. The tyre situation also warrants close attention at the point of purchase. The offside front tyre flagged in March 2025 was carrying a non-deep cut alongside inner-edge wear and perishing, and the nearside front showed cracking; these tyres are therefore likely to be due for replacement imminently due to age-hardened rubber even if tread depth remains acceptable. When inspecting the car, check the date code on each tyre and look for shoulder or inner-edge feathering, particularly on the fronts, which would suggest camber or tracking issues consistent with the four-wheel edge-wear pattern observed in 2021. On a road test, pay attention to steering pull to one side, vague turn-in response, or tramlines over uneven surfaces, as these can indicate worn front suspension bushes or track rod ends. A full four-wheel alignment check and a fresh set of premium tyres would be a sensible immediate investment, alongside the front brake refurbishment, to restore the vehicle to a confident roadworthy state.
