2021 Audi A5 Sport 35 Tfsi Mhev S-A 2.0L Petrol · ND70 JFN

A pattern of rear suspension deterioration sits at the centre of this Audi A5's roadworthiness record, with both rear shock absorbers flagged for serious fluid leaks at the same test in January 2024. The vehicle failed that inspection on a Major defect basis, indicating that the dampers were no longer merely worn but actively compromised and likely beyond serviceable limits. The fact that both units were affected simultaneously suggests a systemic shock absorber issue rather than an isolated seal failure, a concern that warrants particular scrutiny given that replacements are typically fitted in axle pairs to preserve handling balance. Following the failure, the vehicle subsequently passed both the 2025 and 2026 tests without any recorded advisories, suggesting that remedial work was carried out, though the MOT record does not confirm whether original-equipment or aftermarket dampers were fitted. Annual mileage of around 4,531 miles over five years is notably low for a vehicle of this age, and the four recorded tests between January 2024 and February 2026 show a consistent pattern of testing with no extended off-road gaps. This profile points to light, intermittent use rather than a long lay-up, which reduces the likelihood of issues commonly associated with prolonged standing such as brake disc corrosion, brake caliper seizure, or 12V battery deterioration. Mechanically, the low mileage should have preserved most wear-related components, and the absence of recurring advisories across the two most recent passes supports the view that major consumables are not yet heavily worn. However, light use can still produce uneven brake pad and disc corrosion, particularly on a vehicle equipped with an automatic transmission and mild-hybrid system that may encourage gentle driving. With front tyres already recorded at approximately 2.3mm and 2.4mm of remaining tread on the inside edges at the February 2026 test, an immediate priority is a fresh pair of front tyres, and the edge wear pattern should be investigated rather than simply replaced. Edge wear on both sides of the front axle is frequently associated with incorrect wheel alignment, worn suspension bushes, or weakened top mounts, so a four-wheel alignment check should be requested alongside the tyre renewal. On a test drive, listen for any knocking or clonking from the front suspension over speed humps and uneven surfaces, and pay particular attention to steering precision; any vagueness, drift, or tramlining could point to the underlying cause of the uneven tyre wear. Also confirm that the wheel alignment readings are within Audi's specified tolerances before accepting the vehicle. The rear suspension, having previously failed on both shock absorbers, deserves direct verification on inspection. With the vehicle unladen, push down firmly on each rear corner and release; the body should rise and settle without continuing to oscillate more than once or twice, and any prolonged bouncing or asymmetry between the two sides could indicate that the replacement dampers are themselves degraded. Listen for any fluid seepage around the rear damper bodies or at the top mounts inside the boot area, and inspect the rear brake discs for any lip corrosion that may have developed during light use. Finally, verify that the mild-hybrid 48V system shows no warning messages on the instrument cluster, as electrical faults on MHEV components are not assessed under MOT but can be costly to rectify.
