2021 Audi Q3 S Line 35 Tfsi Mhev S-A 1.5L Petrol · BV71 EBD

The vehicle passed its most recent MOT test on 29 August 2026 with no defects or advisories recorded, representing a clean pass at the conclusion of the available testing data. However, the trend across the recent history warrants close scrutiny, as the 2025 test sequence showed a notable deterioration prior to the clean pass. In August 2025, the vehicle initially failed on two major defects concerning the front and rear registration plates not conforming to specified requirements, alongside several advisories, before passing on the same date once the plate issues were rectified. The advisory items raised in 2025, namely tyre perishing on both rear tyres and light oil misting on the nearside front shock absorber, were not carried forward as defects in 2026, suggesting either remedial attention or that the issues remained within acceptable tolerance. The shift from active defects and advisories in 2025 to a completely clean pass in 2026 suggests that the vehicle is currently in a stable mechanical condition, though the rapid turnaround between the failure and pass on the same day in 2025 indicates the corrective work was relatively minor and primarily administrative in character. Overall, the maintenance trajectory appears to have improved, but the cumulative advisories from 2024 and 2025 still provide useful guidance for a prospective buyer. The recorded mileage of 40,254 miles over a five-year period equates to approximately 8,051 miles annually, which is broadly typical for a vehicle of this age and class. There are no significant gaps in the recorded mileage progression that would suggest prolonged periods of standing, nor is there evidence of unusually rapid accumulation that might point to excessive motorway or high-load use. This average annual mileage implies that wear-related components such as brake pads, discs, tyres, and general suspension items should have experienced moderate, predictable degradation rather than accelerated fatigue. The relatively modest annual mileage is favourable for long-term mechanical integrity, particularly concerning the mild-hybrid 35 TFSI powertrain, which is likely to have been subjected to regular but not arduous use. A consistent usage pattern such as this generally supports better longevity of timing chains, turbocharger components, and dual-clutch or automatic transmission elements than would be expected from a vehicle covering significantly higher annual distances. Despite the clean 2026 pass, the advisory history from 2024 and 2025 provides several clear pointers for physical inspection. The nearside front shock absorber light oil misting noted in 2025 is a particularly important item to investigate, as shock absorbers progressively degrade once their oil seal integrity is compromised. A test drive over varied road surfaces, including speed humps, uneven tarmac, and gentle cornering, should be conducted to listen for any clonking, knocking, or excessive bouncing that would indicate the damper has deteriorated beyond the light misting stage. Additionally, the vehicle should be inspected for uneven front tyre wear, which could point to worn suspension bushes, top mounts, or tracking irregularities. Although no such advisories were raised in 2026, a five-year-old vehicle with the recorded mileage would benefit from a close examination of all suspension bushes, anti-roll bar drop links, and wishbone bushes for perishing or splitting, as rubber components degrade with age irrespective of mileage. The rear tyre perishing advisories from 2025 warrant particular attention, as tyre sidewall cracking from age-related rubber degradation can affect a vehicle even when tread depth remains adequate. Although fresh tyres were apparently fitted between the 2025 and 2026 tests, the buyer should verify the age codes on all four tyres to ensure none exceed five years from manufacture, as older tyres can suffer compromised structural integrity even with low wear. The brake system should be inspected for disc corrosion and any signs of binding calipers, particularly given the typical annual mileage which allows for periods of standing in winter conditions. Given the calendar age of the vehicle, the prospective buyer should also confirm the service history includes recent renewal of brake fluid, which is time-sensitive regardless of mileage, along with coolant and the oil change interval being within manufacturer specification. The 12V battery, supporting the mild-hybrid system, should be tested for state of charge and cranking performance, as auxiliary battery failures are common in vehicles with start-stop and mild-hybrid functionality. Finally, a thorough road test should be conducted to verify the automatic gearbox operates smoothly throughout all ratios, the MHEV system engages without warning lights, and there are no unusual vibrations or hesitation that could indicate developing issues with the hybrid architecture or engine management systems.
