2018 Audi Q7 3.0L Diesel · YM18 OSK

The most recent MOT, carried out on 15 May 2025, resulted in a failure. The failure was triggered by a major defect on the off‑side front tyre – a cut that has progressed through to the ply – and by an advisory on the near‑side front tyre for a similar, though shallower, cut together with tread wear approaching the legal limit. Earlier tests show a pattern of tyre‑related defects and occasional minor issues such as a faulty washer system and tailgate lamp irregularities. While the 2024 test passed, it still recorded an advisory for a front‑tyre cut, indicating that the tyre condition has not improved and, in fact, has deteriorated to the point of a failure. Overall the maintenance trend is therefore worsening, principally in the tyre and wheel‑related areas. The odometer reads 57,285 mi for a vehicle first registered in 2018, giving an average annual mileage of roughly 7,150 mi. This figure sits comfortably within the typical UK usage band of 7‑10 000 mi per year and suggests the car has not been subjected to excessive short‑trip wear or high‑stress driving. There are no obvious gaps in the recorded mileage that would imply long periods of storage, so the wear observed is likely a consequence of normal use rather than prolonged standing. Nevertheless, the relatively low cumulative mileage means the tyres are now eight years old, and rubber degradation can be significant even at modest distances. A prospective buyer should give immediate attention to the front tyre set. Both front tyres exhibit cuts that have either reached or are close to reaching the reinforcing cords, a condition that can lead to sudden loss of pressure or a blow‑out, especially at highway speeds. The buyer should verify the exact tread depths, inspect the sidewalls for dry‑rot, cracking or bulging, and arrange for replacement of the front tyres as a priority. The rear tyres are also flagged as being close to the legal limit, so measuring their tread and assessing age‑related hardening is advisable; replacing the rear set may be prudent if the sidewalls show signs of perishing. During a test drive, listen for any vibration or thumping that could indicate a damaged tyre or wheel, and feel for any pull to one side which might point to uneven tyre wear or mis‑alignment. Beyond the tyres, the MOT notes a deteriorating rear registration plate and a damaged off‑side rear reflector – both should be replaced to avoid future failures. The washer‑fluid pump was previously deemed insufficient, so confirm that the system now delivers an adequate spray and that the reservoir is not leaking. The intermittent tailgate lamp fault noted in 2022 should be checked, as electrical gremlins can indicate corroded connectors. Given the vehicle’s age, inspect the 12 V battery for sulphation, verify the condition of the brake discs for surface rust or glazing, and ensure that all fluid levels (engine oil, coolant, brake fluid and transmission fluid) have been refreshed in accordance with the service schedule, as calendar‑based degradation can occur even with modest mileage. A thorough visual inspection of suspension bushes, control arm joints and shock absorbers is also recommended, as uneven tyre wear may have been accelerated by worn bushings. If all these items are addressed, the Audi Q7 can remain a reliable, comfortable family SUV.
