2020 Audi Q7 S Line 50 TDI Mhev Quat A 3.0L Diesel · LR20 WHV

A recent tyre-related failure in October 2025 is the only blemish on an otherwise clean MOT record for this 2020 Audi Q7. The vehicle passed its most recent test on 23 October 2025 with no defects recorded, just five days after failing on a Major defect for an offside rear tyre with a cut deep enough to expose the ply or cords, alongside advisories for an offside front nail in tyre and a nearside rear tyre with a shallower cut. That single failure is an isolated tyre condition issue rather than a structural or mechanical defect, and the surrounding tests from 2022, 2023 and 2024 all passed cleanly. The only other recorded advisories were at the 2024 test, where both front tyres were noted as worn close to the legal limit at 3mm and worn on the edge, suggesting the fronts had been run close to the tread limit prior to replacement. The overall trend is one of stable roadworthiness with no repeat advisories across the same components from year to year. With 56,232 miles accumulated over roughly six years, this Q7 averages around 9,372 miles annually, which is broadly typical for a large premium SUV of this age and neither unusually low nor excessively high. There are no extended gaps in the testing record and no sudden jumps in mileage between tests, indicating consistent usage rather than long periods off the road or rapid accumulation that might suggest heavy commercial or motorway use. This mileage band places the vehicle in a zone where factory-fitted suspension bushes, anti-roll bar links, dampers and brake components are beginning to show meaningful wear but are not yet at the point of predictable replacement on most examples. The consistent testing pattern also means there are no multi-year lay-up concerns such as seized brakes, perished coolant hoses or deteriorated underbody rubber to specifically anticipate. For a prospective buyer, the priority areas to inspect on a physical viewing are the four tyres, including the spare if a spacesaver or inflation kit is present, as the record shows both sudden impact damage from a nail and accelerated inner-edge wear on the front pair. Measure tread depth across the full width of each tyre rather than just the centre, as the 2024 advisory specifically flagged edge wear which can indicate alignment or suspension geometry issues. On the test drive, listen for any knocking or clonking from the front suspension over uneven surfaces, which could point to worn top mounts, anti-roll bar drop links or control arm bushes given the mileage, and pay particular attention to steering vagueness or a slight pull that may have contributed to the earlier edge wear. Inspect the brake discs through the wheels for lipping on the outer edge and check for any binding or juddering under firm pedal application, as these are common wear items at this mileage on a heavy SUV. Underneath the vehicle, a torch-led inspection of the front subframe mounting points, suspension arms and brake pipe runs is worthwhile given UK climate exposure and the fact that corrosion advisories often begin appearing on premium SUVs once they pass the five-year mark, even when not yet recorded at test. Examine the rear silencer and exhaust mounting rubbers for any signs of deterioration, and check the engine bay and undertray for evidence of oil misting or weeping from the 3.0 V6 TDI unit, particularly around the timing chain cover and turbo oil feed lines which are known wear points on this engine family. Finally, verify that the tyre fitment on all four corners is consistent in brand, size and age, as mismatched tyres can both cause an MOT failure and indicate a reactive rather than proactive replacement history, and confirm that the recent offside rear tyre replacement after the 2025 failure was carried out with a matching specification.
