2015 Audi A5 3.0L Diesel · OV64 SWY

The most recent MOT, carried out on 24 September 2025, was passed but recorded advisories concerning fluctuating service‑brake readings on both front wheels (1.2.1 (e)). Earlier in the series, a failure on 27 September 2023 was recorded for a dangerous fracture of the nearside rear inner wheel and tyre wear close to the legal limit on both rear wheels, while a 4 March 2022 advisory noted slight distortion of the nearside front road wheel. Since that serious incident the vehicle has achieved three consecutive passes, the only recurring notes being minor wheel‑related advisories and the latest front‑brake fluctuation, suggesting that the most acute structural problems have been remedied and the overall maintenance trajectory is now stabilising, albeit with lingering wear that warrants close scrutiny. At 154 229 miles the car has averaged roughly 14 000 miles per annum over its eleven‑year life, a mileage rate well above the typical UK average for a vehicle of this age. Such utilisation accelerates wear on consumables such as tyres, brake pads, rotors and suspension bushings, and can also hasten fatigue in engine and transmission components. The relatively high annual mileage, combined with the previous rear‑wheel failure, indicates that the drivetrain and rear axle have been subjected to significant load cycles and should be examined for signs of bearing play, axle shaft wear and any abnormal noises under load. When inspecting the car, pay particular attention to the rear wheels and tyres. Verify that the fractured nearside rear wheel has been replaced with a genuine, correctly balanced unit and that the off‑side wheel, which has undergone two inner repairs, shows no signs of cracking, corrosion or out‑of‑round run‑out. Examine the tyre tread depth across all four tyres, looking for uneven wear that could betray mis‑alignment, worn suspension bushes or failing rear‑axle components; listen for a hollow thump or feel a vibration when applying the brakes, which may indicate warped discs or loose calipers. Check the front brake system for any pulsation or inconsistent pedal feel that could be linked to the reported fluctuation, and inspect pads and discs for uneven wear or glazing. A thorough visual inspection of the suspension should include the condition of the front and rear control‑arm bushings, the coil‑spring integrity and any signs of leaking shock absorbers, as high mileage often leads to bushings becoming soft or cracked, resulting in clunking noises over bumps. Given the vehicle’s age, also confirm the health of time‑sensitive items. The 12‑volt battery should be tested for cranking amps, as prolonged standing can cause sulphation; look for any corrosion on terminals. Verify that the engine oil, coolant and brake fluid have been changed within the manufacturer’s calendar intervals, as fluids degrade even when the car is not driven heavily. Inspect the under‑carriage for rust, especially around the wheel arches and suspension mounting points, and ensure that the exhaust system is free of cracks or excessive rust that could affect emissions compliance. Finally, request a full service history to corroborate that regular oil changes, filter replacements and any major service milestones (such as timing‑belt or chain replacement) have been observed, which will give you greater confidence in the car’s long‑term reliability.
