2018 Audi Q5 2.0L Diesel · SR11 ANR

A clear pattern of late-life consumable wear defines the mechanical picture of this 2018 Audi Q5, with the most recent test on 27 April 2026 passing but carrying four brake pad advisories across both axles and a deteriorating driveshaft boot. Up until that 2026 examination, the vehicle had enjoyed a notably clean advisory history, with only a front tyre edge-wear advisory in May 2024 and standard engine cover or undertray fitment notes in 2023 and 2024 masking otherwise defect-free results in 2022 and 2025. The sudden cluster of brake and drivetrain advisories in the latest test suggests that the consumable wear envelope has been reached, which is consistent with a higher-mileage SUV approaching the second half of its first decade. While a pass is a pass, the density of advisories on a single test is a meaningful signal that several service items now require attention before they progress into failure territory. With 90,463 miles recorded over roughly eight years, this Q5 has averaged around 11,300 miles per year, which sits comfortably within typical UK usage for a vehicle of its age and class. There are no significant gaps in the MOT history that would imply extended periods off the road, and the mileage accumulation between consecutive tests is broadly consistent rather than erratic. For an Audi Q5 of this generation and mileage band, the mechanical expectation is that suspension components, brake system hardware, drivetrain couplings, and engine ancillary items will be entering their mid-life wear phase. The fact that the test history shows no MOT failures across five recorded examinations does suggest that the vehicle has remained roadworthy throughout its life, but it does not confirm mechanical soundness beyond the specific items examined at the time of testing. For a prospective buyer, the immediate priority is a thorough inspection of the brake system, given that all four pad sets were flagged as wearing thin in April 2026. A test drive should focus on pedal feel and response: any soft pedal travel, excessive pedal effort, or judder under firm braking would suggest that the discs have worn in tandem with the pads and may also require replacement. Listen for binding or scraping noises from the calipers, particularly after the brakes have been used heavily, as sticking calipers are a common failure point on Q5s of this era. Inspect the rear brake disc surfaces for lipping and check for any uneven wear pattern that could point to a seized caliper slide or handbrake mechanism. Given the rear inner driveshaft CV boot was recorded as severely deteriorated, the buyer should also have the drivetrain raised and inspected for grease loss at the joint, listening for any clicking or vibration on full-lock turns during the test drive as an indicator that the boot failure has already allowed contamination ingress. Beyond the directly flagged items, the high annual mileage combined with the recent cluster of advisories warrants closer examination of the suspension and underbody. On the road, pay particular attention to any knocking or clonking noises from the front suspension over uneven surfaces, as Q5s of this age are known for wear in the front lower control arm bushings and anti-roll bar drop links. Steering should feel precise and well-damped, with no vibration, pulling, or delay on turn-in. With the engine covers and undertrays recorded as fitted on multiple tests, the buyer should ensure these are removed for a pre-purchase inspection so that any oil leaks from the engine sump, timing chain area, or coolant pipes can be properly assessed. A final visual check of the underside for any corrosion to subframe mounting points, brake lines, and exhaust mounting rubbers will round out a sensible appraisal of a high-mileage Q5 whose consumables are now clearly demanding attention.
