2017 Audi Q5 S Line TDI Quattro S-A 2.0L Heavy oil · AE67 TZB

Corrosion on the rear suspension mounting points and spring cups represents the primary mechanical concern for this vehicle, as these issues have appeared in consecutive tests. While the most recent test on 12 January 2026 resulted in a pass with no defects, the preceding records from 2024 and 2025 specifically flagged corrosion on both rear lower suspension arm attachment brackets and the rear lower spring mounting cups. This indicates a recurring pattern of structural oxidation in the rear subframe area that requires close monitoring to ensure the corrosion does not progress from an advisory to a structural failure. The vehicle has covered 95,971 miles over its nine-year lifespan, averaging approximately 10,663 miles per year. This usage profile is consistent with typical UK annual mileage for a premium SUV of this age. Such steady accumulation suggests the vehicle has been in regular use rather than sitting stationary for extended periods, which generally means mechanical components like seals and bearings have been regularly lubricated through operation, though it also implies a predictable level of wear on consumable items such as tyres, brake discs, and suspension bushes. Prospective buyers should pay close attention to the rear suspension during a test drive. Given the history of corroded mounting brackets and spring cups, listen for any rhythmic knocking, clunking, or metallic banging sounds when driving over uneven surfaces or speed bumps, as these can indicate that the corrosion is affecting the integrity of the suspension mounts or the bushes. Additionally, the 2024 record noted front tyres being worn close to the legal limit and out of shape; during the test drive, check for any steering pull or vibrations through the steering wheel, which could indicate uneven tyre wear or alignment issues resulting from the previously flagged suspension component wear. Braking components have also been a recurring theme in the advisory history, with records from 2021 and 2023 noting significant wear and pitting on both front and rear brake discs. Although the 2026 test showed no immediate defects, the history of worn and scored discs suggests that the braking system undergoes regular wear cycles. On a test drive, feel for any pedal judder or pulsation when applying the brakes at speed, and listen for any squealing or grinding noises that might indicate the pads are nearing the end of their service life or that the discs have become unevenly worn.
