2017 Audi Q7 3.0L Diesel · WN67 WHA

A clean and uninterrupted run of pass certificates, culminating in a defect-free test on 1 October 2025, establishes this Q7 as a notably well-maintained example within its cohort. Across five consecutive MOT entries covering the period from 2021 through late 2025, no failures or dangerous defects have been recorded, and only two advisory items have ever been raised, both of a minor nature in 2023. The trajectory is one of stable, reassuring roadworthiness rather than any pattern of deterioration, and the absence of structural, corrosion, or exhaust-related advisories is particularly relevant given the Q7's known susceptibility to underbody and subframe corrosion in UK operating conditions. The recorded odometer reading of 40,143 miles against a nine-year registration places this vehicle in genuinely low-accumulation territory, equating to roughly 4,460 miles per year on average. This is well below the typical mileage profile for a large premium SUV of this vintage and warrants consideration of how the vehicle has actually been used. The MOT records display no abnormal step-changes or unusual gaps, with tests conducted on a consistent annual cadence and mileage progression appearing steady between examinations. Light usage of this nature typically preserves the braking system, drivetrain components, and interior trim, but it can equally suggest extended periods of inactivity, which places particular demand on items sensitive to standing — most notably the 12V auxiliary battery, brake fluid condition, and tyre integrity, especially where cold inflation pressures may have dropped repeatedly during storage. Tyres more than five or six years old, irrespective of tread depth, should be carefully examined for perishing and sidewall cracking. The 2023 advisory concerning a slightly damaged nearside front tyre should prompt close inspection of the current set, checking for any uneven shoulder wear, bulges, or impact damage that might suggest kerbing or pothole contact. Any replacement tyres fitted should be of matching size and load rating on both axles, as the Q7's all-wheel drive system and stability control calibration are sensitive to rolling circumference differences. The second 2023 advisory noted rear brake pads wearing thin; with the vehicle now a further two test cycles and potentially several thousand miles beyond that point, the rear pads will almost certainly require replacement in the near term, and it would be prudent to confirm whether the rear discs were also addressed at the same time or show signs of lipping or surface corrosion. On a test drive, listen for any binding or dragging sensation from the rear calipers, particularly when first pulling away from cold, and verify that the handbrake holds firmly on an incline. Beyond those flagged items, a low-mileage Q7 of this age merits specific attention to areas not always surfaced by the MOT cycle. On a road test, listen for clonks or knocks from the front suspension over uneven surfaces, which could indicate worn upper or lower control arm bushes, anti-roll bar links, or top mount bearings — components that degrade with age and standing time as much as with mileage. Inspect the engine bay and undertrays for any signs of oil misting around the cam chain cover, turbo oil feed lines, or the V6 TDI injectors themselves, and verify that the diesel particulate filter has been actively cycling, ideally evidenced by recent motorway running rather than exclusively short journeys. Finally, confirm that all warning systems, including the AdBlue level and emissions-related indicators, function correctly at start-up, and that the infotainment and driver assistance systems — adaptive cruise, lane assist, and parking sensors — operate without fault codes, as rectification of these electrical subsystems can be disproportionately costly on premium vehicles of this class.
