2011 Audi A5 2.0L Diesel · MM11 MWD

The 2011 Audi A5 presents a mixed maintenance profile, trending toward deterioration in recent years despite passing its most recent MOT on 12 November 2025 at 138,226 miles. The latest test flagged worn and pitted offside rear brake discs alongside a severely deteriorated offside front outer constant velocity boot. This CV boot defect has persisted since at least 4 December 2024, indicating a worsening trend where a known vulnerability was left to degrade over twelve months and 4,549 miles. Passing the 2025 test with these items suggests they fell just within acceptable limits, yet the ongoing nature of the fault points to deferred mechanical rectification by the previous keeper. Accumulating 138,226 miles over fifteen years equates to roughly 9,215 miles annually, a typical usage figure for this age of vehicle. The record shows consistent annual testing without significant gaps in the provided history. Mileage accumulation accelerated slightly between 2023 and 2024, jumping 10,130 miles between 4 December 2023 and 4 December 2024, compared to the 9,771 miles covered in the preceding twelve months. The most recent year saw a jump of 4,544 miles between 9 December 2024 and 12 November 2025, reflecting a steady but unremarkable driving pattern that keeps consumable wear within expected parameters. A physical inspection must prioritize the offside front outer constant velocity joint. A severely deteriorated boot allows grease egress and dirt ingress, risking joint failure and sudden drivetrain disintegration. Examine the offside rear braking surface closely; pitted and scored discs compromise heat dissipation and braking efficiency, demanding measurement of disc thickness and lip wear. The repeated appearance of front tyre edge wear across 2022 and 2024 tests suggests potential suspension geometry deviation or aggressive cornering habits, requiring a thorough check of suspension bushes and tracking alignment. Verify the structural integrity of the rear light cluster mounting area, given the snapped headlamp levelling link rod noted in the December 2024 failure.
