2016 Audi Q7 3.0L Diesel · 5507 AT

The 2016 Audi Q7 presents a mixed maintenance trend, with the most recent MOT in March 2026 revealing emerging mechanical wear that warrants closer inspection. Passing at 34,419 miles on 26 March 2026, the vehicle acquired fresh advisories for worn and pitted front brake discs alongside surface rust on the central rear lower sections. The recurrence of the rear corrosion advisory, previously noted at the April 2025 test at 29,936 miles, indicates a worsening trend regarding structural integrity rather than a one-off occurrence. While the vehicle remains roadworthy, the repetition of corrosion issues suggests previous owners may have neglected underbody protection or allowed prolonged moisture exposure. Averaging roughly 3,442 miles per year over its ten-year lifespan, this Q7 falls well into the low-mileage category. The mileage progression shows a notable gap between the December 2021 test at 17,354 miles and the January 2023 test at 20,732 miles, representing only 3,378 miles over thirteen months. From January 2023 to March 2026, the vehicle covered 13,687 miles at a slightly higher annual rate, yet the overall usage remains exceptionally light. Such sporadic use often leads to dormant components suffering from dried-out rubber seals or surface corrosion on brake discs, which aligns directly with the pitting noted in the latest assessment. A physical inspection must prioritize the structural condition of the central rear underside, as repeated surface rust advisories can mask deeper corrosion affecting subframes or suspension mounting points. The tester flagged pitted and scored front brake discs during the March 2026 test, meaning buyers should measure disc thickness and check for lipping, while also inspecting the rear braking system for binding calipers given the vehicle's tendency to stand idle. Tyre condition requires scrutiny too. The January 2023 test at 20,732 miles flagged cracking and perishing on both rear tyres, so current rubber must be checked for dry rot, especially if the vehicle has sat unused for extended periods. Suspension bushes and coil springs should be examined for deterioration typical of low-mileage vehicles that spend long periods stationary.
