2021 Audi Q3 Sport 35 Tfsi Mhev S-A 1.5L Petrol · AO21 MZT

The latest MOT test on 2026-05-21 resulted in a failure, with the vehicle failing due to a missing near-side front road wheel fixing, alongside persistent advisories for near-side front and rear tyres showing signs of damage, cracking, or perishing. This marks a clear deterioration from the previous two MOTs, which were passed without any recorded defects, indicating a concerning trend where the vehicle’s structural integrity and tyre condition have progressively degraded over the past two years. The repeated advisories on tyre condition suggest either prolonged standing in adverse environmental conditions—such as exposure to UV radiation, ozone, or road salt—which accelerates tyre sidewall degradation, or excessive wear from aggressive driving or poor alignment. The failure to address the missing wheel fixing further compounds the risk, as a loose or improperly secured wheel could lead to catastrophic failure during operation, posing significant safety hazards. The recorded mileage of 51,634 miles for a vehicle aged five years represents a moderate annual usage rate of approximately 10,327 miles per annum, which is within the expected range for a car of this age and class. However, the lack of a service history or any significant mileage gaps between tests raises questions about whether the vehicle has been subjected to consistent, high-demand driving or if it has been left stationary for extended periods. Prolonged idling or standing in harsh climates can accelerate tyre perishing, particularly on the near-side tyres, as seen in the MOT advisories. Additionally, a stationary vehicle is more susceptible to corrosion on components such as the wheel fixings, brake discs, and suspension linkages, which could explain the missing fixing and potential wear on the wheel bearings or seals. The absence of a service record also means that time-based maintenance, such as fluid top-ups or brake system checks, may not have been performed at the recommended intervals. For the prospective buyer, the most critical inspection should focus on the tyre condition and structural integrity of the near-side wheels and suspension. The near-side tyres showing cracking or perishing warrant immediate attention, as these defects can compromise traction and increase the risk of blowouts. Inspect the tyre sidewalls for signs of dry rot, delamination, or exposed cords, and ensure there is adequate tread depth remaining—though the MOT advisories suggest the issue is more severe than a simple wear advisory. On the wheel fixings, visually confirm the absence of the missing bolt and check for any signs of corrosion or damage to the surrounding wheel hub or brake caliper mounting points. Listen for unusual noises during the test drive, particularly clunks or rattles from the near-side suspension, which could indicate loose or worn suspension bushes, coil spring damage, or binding calipers. If the wheel fixing is indeed missing, the buyer should prioritise replacing it as a matter of urgency to prevent a dangerous situation. In addition to the immediate concerns, the buyer should conduct a thorough inspection of the vehicle’s standing corrosion, particularly on the near-side components, as prolonged exposure to moisture and road salt can accelerate rust formation. Check the brake discs for signs of corrosion, warping, or binding, which could indicate prolonged standing or inadequate lubrication. Inspect the 12-volt battery and associated electrical connections for signs of corrosion or poor contact, as a stationary vehicle is more prone to battery drain or electrical issues. Fluid levels should be checked, with particular attention given to the brake fluid, as standing fluid can absorb moisture and degrade over time, leading to brake system failure. Finally, verify the service book for any scheduled maintenance, such as oil changes or suspension servicing, which may have been overlooked due to the vehicle’s history. If the vehicle has been driven regularly, the wear on brakes, suspension, and drivetrain components may be more pronounced, so a professional inspection is advisable to assess the extent of any hidden damage.
