Buying a used Audi Q8: what to check
These checks follow the Audi Q8’s own MOT record: the areas it fails on most often, and how that changes as the car gets older. None of them replaces a mechanic’s inspection, but they tell you where to look first.
1. Tyres
Recorded in 59.3% of failed Audi Q8 MOTs.
Check tread depth across the whole width of every tyre, including the inner edge. Uneven wear can point to alignment or suspension problems. Look for cuts and bulges in the sidewalls.
2. Number plates and VIN
Recorded in 17.3% of failed Audi Q8 MOTs.
Match the registration plates and the VIN (usually at the base of the windscreen and on a door pillar) to the V5C.
3. Brakes
Recorded in 12.6% of failed Audi Q8 MOTs.
On the test drive, the car should stop straight without pulling or juddering, and the handbrake should hold it on a slope. Look through the wheels for scored or heavily lipped discs.
4. Lights and electrics
Recorded in 11.3% of failed Audi Q8 MOTs.
Walk round with the lights on: headlights (dipped and main), indicators, brake lights, fog light and number-plate lamp. Check the dashboard warning lights come on with the ignition, then go out once the engine starts.
5. Windscreen and wipers
Recorded in 10.9% of failed Audi Q8 MOTs.
Look for windscreen chips and cracks in the driver’s line of sight, and check the wipers clear the screen and the washers work.
Check the car’s own MOT history. Averages describe the model, not the car in front of you. Look up its registration for past failures, advisories that were never fixed, and gaps or dips in the recorded mileage.
Ask for the service history. Invoices show what was done and when; a stamp alone shows less. See how to check Audi service history and what a service history check can tell you.
