2021 Audi Q8 SLN BLK ED 50 TDI Mhev QT A 3.0L Diesel · DF21 HLC

A 2021 Audi Q8 SQ8 Black Edition 50 TDI MHEV Quattro presenting with a clean and largely unblemished MOT record, the only blemish being a single advisory for tyre wear. The most recent test on 29 June 2026 was a pass with no defects recorded, continuing a stable trajectory of roadworthiness that has held since the vehicle was first tested in 2024. Over three consecutive tests there has been one advisory and zero failures, which represents an objectively solid DVSA outcome for a five year old premium SUV. The single advisory concerning all four tyres being worn close to the legal limit suggests that the previous set was approaching the end of its useful service life at the time of the 2025 test, and given typical replacement intervals it is reasonable to assume new tyres were fitted shortly afterwards. With 49,129 miles recorded against an age of roughly five years, this Q8 has covered approximately 9,800 miles annually, a figure broadly consistent with average UK vehicle usage for this class. There are no significant gaps in the testing history that would suggest extended periods off the road, and the progression between tests appears consistent with steady mixed driving rather than any unusual accumulation patterns. From a mechanical standpoint, this level of annual mileage means the consumables and wear items typical of a heavy diesel premium SUV such as brake pads, discs, tyres and suspension components will have experienced moderate but realistic working life. It is neither an alarmingly high mileage that would flag imminent major mechanical intervention nor a particularly low figure that raises concerns about dormant component degradation. Given the advisory recorded for all four tyres being worn close to the legal limit and on the edge, a prospective buyer should inspect the current set carefully, checking the tread depth across the full width and shoulder of each tyre, as edge wear specifically can indicate alignment issues, suspension geometry wear or aggressive cornering loading on a heavy Quattro-driven vehicle. On a test drive, listen for any drone or uneven road noise that could suggest uneven tyre wear, and verify that the steering remains centred with no pull to either side, which could point to geometry concerns stemming from the previously noted edge wear pattern. Beyond the tyre observation, the test drive should focus on the areas most likely to show wear on a vehicle of this age and specification. Listen for any clonks or knocking from the front suspension when traversing speed bumps or uneven surfaces, paying particular attention to the control arms, anti-roll bar links and top mount bearings. Check for brake pedal judder under firm application, which may indicate disc warping, and listen for any scraping or grinding that could suggest worn pads contacting the discs. Given the MHEV 48-volt architecture, the engine start-stop system should be evaluated for smooth re-engagement, and the diesel engine should be observed for any excessive vibration, smoke from the exhaust under load, or delay in turbocharger response. Finally, inspect the underside of the vehicle for any signs of oil misting or weeping from the engine, transmission or rear differential seals, all of which are areas that can show early signs of age on a Quattro drivetrain of this mileage.
