2017 Audi Q7 3.0L Diesel · YY67 CHC

A consistent pattern of brake-related advisories across four consecutive MOT tests defines the mechanical profile of this 2017 Audi Q7, with front and rear pad wear flagged at each annual inspection from 2021 through 2023. The most recent test on 8 October 2025 returned a clean pass with no advisories recorded, suggesting the braking system has likely received attention through replacement pads, and the trend over the past two cycles indicates stable roadworthiness. However, a prospective buyer should not interpret this clean pass as evidence that the discs and pads are new; on a high-mass SUV such as the Q7, brake discs wear in tandem with pads, and a previous thin-pad condition left unaddressed can score the disc surface or accelerate disc wear. The single offside bodywork damage note from 2023 is cosmetic rather than structural, but warrants a close visual check for any subsequent repair quality, corrosion initiation around the damaged area, or evidence of accident rectification. With 85,336 miles recorded over approximately nine years, the vehicle accumulates around 9,480 miles annually, which sits broadly in line with typical UK usage for a large family SUV. The mileage progression between tests appears steady and consistent, with no sudden spikes that would suggest tow-heavy use, long-distance motorway commuting, or conversely, extended periods of standing which could promote corrosion in undertrays, brake calipers, and exhaust mounting rubbers. This average annual mileage implies moderate wear on suspension components, drivetrain mounts, and air suspension elements if fitted, none of which have been recorded as failing or wearing at MOT, though this does not preclude deterioration of rubber bushes, anti-roll bar links, or coil springs at this age and mileage. On a physical inspection, particular attention should be paid to the front and rear brake discs and pads, measuring disc thickness against the manufacturer minimum and checking for lipping, hot spots, or corrosion pitting on the disc face which can cause pedal pulsation under firm braking. The brake pad warning light advisory from the same period suggests the pad wear sensor may have been replaced or the pads renewed, so confirm whether the sensor wiring is intact and that no warning remains illuminated on the dashboard. Beyond the braking system, listen for clonks or knocks from the front suspension over speed bumps, particularly from upper and lower wishbones, drop links, and anti-roll bar bushes which on the Q7 are known wear items and can deteriorate without triggering an MOT failure until play becomes excessive. Check for any pulling under braking, inconsistent pedal feel, or vibration through the steering wheel which would indicate warped discs, seized caliper slider pins, or a flexible brake hose swelling under pressure. Finally, inspect the offside bodywork area previously flagged for damage, looking for paint thickness inconsistencies with a gauge, evidence of filler, or poor panel alignment that might suggest a substandard cosmetic repair. Examine the underside, including subframe mounting points, suspension arms, and brake pipe runs, for any surface corrosion given the vehicle's age and the UK's wet, salt-laden road conditions. A thorough test drive should include a cold start to observe for excessive smoke, engine misfires, or diesel knock if this is the TDI variant, and a sustained drive over varied surfaces to allow the transmission, all-wheel-drive system, and suspension to reach operating temperature. Any warning lights remaining on the instrument cluster, particularly the brake, emissions, or suspension systems, should be investigated before purchase.
