2013 Audi A4 2.0L Diesel · OU63 OAW

The 2013 Audi A4 presents a mixed maintenance picture. The most recent MOT on 1 April 2026 at 148,340 miles passed, but only with two advisories for rear tyres worn close to the legal limit and worn on the edge. This follows a pattern of recurring tyre wear issues and a notable failure in March 2024 for excessive exhaust emissions, which was rectified by the retest on the same day. The trend is one of basic compliance rather than proactive upkeep, with consumable items like tyres and wiper blades repeatedly flagged at the point of testing rather than replaced in advance. The mileage progression tells a clear story of consistent, high-mileage use. The car covered 10,299 miles between March 2023 and March 2024, then a further 13,462 miles in the following year to March 2025, before jumping to 148,340 miles by April 2026. That final leap of 20,433 miles in just over twelve months indicates a period of intensive use, likely long-distance commuting or motorway driving. The annualised average of roughly 11,400 miles is typical for the model, but the recent acceleration places additional stress on suspension, brakes, and drivetrain components that a buyer should verify carefully. The March 2024 test exposed several mechanical concerns beyond tyres. Both front upper suspension arm pins or bushes were worn, the offside rear shock absorber had a light misting of oil, and the offside rear brake was binding. The offside rear brake pads were also wearing thin. These items were flagged as advisories rather than failures, meaning they were not severe enough to fail the test at that point, but their presence at 114,441 miles on a vehicle with a clean bill of health just a year earlier suggests either a period of neglected maintenance or accelerated wear from the high mileage that followed. A buyer should have the front suspension arms, rear shock absorbers, and rear braking system inspected for deterioration, particularly the offside rear caliper which showed binding behaviour. The recurring tyre wear advisories across multiple tests point to a persistent alignment or suspension geometry issue. Both rear tyres have repeatedly worn on the edge, and in 2024 all four tyres were flagged simultaneously with splits and sidewall damage. This pattern is inconsistent with simple neglect and suggests the tracking or suspension bushes are allowing uneven contact patches. A four-wheel alignment check and close inspection of the front and rear suspension bushes, ball joints, and any subframe corrosion should be carried out before purchase. The exhaust emissions failure in 2024, while resolved, also warrants attention to the condition of the catalytic converter and lambda sensors given the high mileage now on the clock.
