2012 Audi A4 2.0L Diesel · YA12 TYU

The latest MOT test in March 2022 resulted in a pass, but the history reveals a concerning trend of recurring and escalating defects. The vehicle failed twice in quick succession in early 2022 and late 2021, with major issues including a serious fluid leak from the nearside rear shock absorber and excessive binding of the nearside front service brake. These failures, combined with repeated advisories for worn brake discs, thinning brake pads, and tyre wear, suggest a pattern of deferred maintenance rather than proactive upkeep. While the 2022 pass indicates some remedial work was carried out, the persistence of brake and suspension advisories points to ongoing wear that will likely require attention soon. At 14 years old with 94,780 miles, the annual mileage of around 6,770 miles is typical for a vehicle of this age, indicating neither excessive use nor prolonged inactivity. However, the concentration of failures and advisories in recent years suggests that higher-mileage wear items such as suspension components, brakes, and tyres are reaching the end of their service life. The consistent mileage accumulation without significant gaps implies steady use, which, while not excessive, still demands vigilance regarding age-related degradation of rubber bushes, seals, and corrosion-prone areas. A test drive should focus on the suspension and braking systems, given the history of shock absorber leaks and brake binding. Listen for clunking or knocking noises over rough surfaces, which could indicate worn suspension bushes or failing shock absorbers, and check for uneven tyre wear or excessive bouncing after hitting a bump. Pay close attention to brake performance, as the binding issue and worn discs suggest potential caliper or slide pin seizing, which may manifest as uneven braking, judder through the pedal, or the vehicle pulling to one side. Inspect the tyres for uneven wear, particularly on the inner or outer edges, and verify that all tread depths exceed the legal minimum of 1.6mm, as the history shows a tendency for tyres to wear close to or below this limit. Additionally, examine the underbonnet and underbody for signs of fluid leaks, particularly around the rear shock absorbers, and check the condition of brake hoses and pipes for corrosion or deterioration. Given the vehicle’s age, assess the 12V battery health, as original or older units may struggle with cranking power, and inspect for perished rubber components such as coolant hoses, drive belts, and suspension bushes. Verify the service history to ensure that time-based fluids, including brake fluid, coolant, and differential oil, have been refreshed, as these degrade regardless of mileage. Structural corrosion, particularly in wheel arches, sills, and subframes, should also be inspected, as this can compromise safety and lead to costly repairs.
