2011 Audi A5 3.0L Diesel · XP09 KER

The Audi A5 has maintained a consistent pass rate across its last four MOT tests, but the September 2025 test reveals a clear trend of worsening suspension and brake wear, despite no major failures. The tester flagged multiple worn suspension bushes—front upper and lower arms on both sides—alongside oil misting in the rear and front shock absorbers, indicating progressive degradation. Notably, the rear brake discs and pads were described as worn, pitted, or thinning, suggesting they are approaching critical service limits. While no defects were recorded in June 2022, the subsequent tests show a steady accumulation of advisories, particularly in the suspension and tyres, implying deferred maintenance rather than sudden mechanical failure. The vehicle’s mileage accumulation—149,948 miles over 15 years—averages roughly 10,000 miles annually, which is typical for its age but masks a concerning pattern. The last three MOTs, spaced roughly 12 months apart, show mileage increases of 11,901 (2023–2024) and 12,901 (2024–2025), suggesting consistent but not excessive use. However, the absence of any defects in 2022 followed by repeated advisories in later tests hints at either delayed servicing or a previous owner prioritising short-term compliance over proactive maintenance. The recurring issues in the suspension and tyres—particularly the edge wear—point to alignment or tracking problems that have persisted for years. A prospective buyer should prioritise an independent inspection of the suspension components, focusing on the front upper and lower arm bushes, as well as the shock absorbers for signs of leakage or binding. The rear brakes, particularly the discs and pads, should be checked for uneven wear or scoring, as these are now at a high-risk threshold. Tyre condition demands immediate attention; the inner-edge wear on multiple wheels suggests misalignment, which could accelerate further suspension damage. Finally, the constant velocity boot on the front outer drive shaft, noted as severely deteriorated in 2024, may require replacement to prevent long-term drivetrain issues. Given the vehicle’s age and the volume of advisories, a full service history—especially for brakes and suspension—would be essential before purchase.
