2009 Audi A3 1.9L Diesel · SA09 XSN

A pattern of progressive wear, rather than any outright structural concern, defines this 2009 Audi A3's MOT history. Across eight recorded tests since 2017, the vehicle has passed on every occasion except one early failure in November 2017 for a non-functioning offside rear registration plate lamp and nearside rear inner brake pads worn to below 1.5 mm. The most recent test on 8 July 2024 recorded a clean pass with no advisories or minors, which on the surface suggests improving roadworthiness. However, the intervening years reveal a recurring theme of front tyre wear approaching the legal limit, anti-roll bar linkage bushes wearing at the rear, and minor cosmetic or electrical items such as seatbelt stalk covers and rear position lamps. None of these items have escalated into a failure since 2017, but the chronic nature of certain advisories indicates components that are slowly deteriorating rather than components that have been rectified. With 145,249 miles recorded across approximately seventeen years, this A3 has averaged around 8,544 miles per year, which is broadly typical for a car of its age. There are no obvious extended gaps in the testing record, although the absence of an MOT entry between 2022-11-19 and 2024-07-08 represents a nineteen-month interval that warrants clarification regarding whether the vehicle was in use, laid up, or simply exempt from testing during a portion of that window. The mileage progression between tests is otherwise steady and there are no sudden jumps that would suggest clocking concerns, but the cumulative wear implied by seventeen years of road use places genuine demand on suspension components, brake hardware, drivetrain mounts, and rubber items that the MOT checks only on a visual basis. Given the repeated advisories on the rear anti-roll bar linkage pins or bushes, this is the single most important mechanical item to probe on a test drive. With both sides having been flagged as worn in 2018 and again in 2019, the bushes may have been replaced since, but if not, expect to hear clonks or knocks from the rear suspension over uneven surfaces, accompanied by a slightly loose or imprecise feel during direction changes at speed. On the road, corner briskly over undulating tarmac and listen for any secondary rattle from the rear axle area. Also pay attention to the brake pedal, particularly under firm application from speed, as the 2017 failure on nearside rear inner pads suggests the inner pads on the rear calipers should be physically inspected for remaining friction material, since inner pads can wear at a different rate to outers and are easy to overlook. Any vibration, pulling, or judder through the steering wheel under braking would warrant disc inspection. The chronic front tyre advisories from 2017 and 2020 also merit close attention, particularly as the offside front tyre has been flagged on three separate occasions for being either close to the legal limit, worn on its edge, or suffering cracking and perishing. On a test drive, any steering pull to one side, particularly under braking, could indicate uneven tyre wear or a suspension geometry issue, and the offside front should be examined closely for inner-edge wear, which often points to worn suspension components further back in the chain. Additionally, the 2019 advisory noting a rusted-through central exhaust clamp, while not having reappeared since, suggests the exhaust system deserves a physical check for security, hangers, and corrosion, particularly around the centre and rear silencer areas where road salt collects. Finally, confirm the seatbelt stalks themselves are fully functional despite the broken covers previously recorded, and verify that both rear position lamps illuminate correctly, as the minor defects noted in 2019 and 2020 indicate a tendency for those bulbs to fail intermittently.
