2019 Audi Q8 — MOT failures & pass rate
7,506 MOT tests on the 2019 Audi Q8 are in this dataset, and 92.4% of them passed. That is 2.2 percentage points better than large SUVs of a similar age, which fail at 9.8%. Failures cluster in tyres, visibility and emissions & environmental.
What the MOT record shows
One area stands out: tyres, recorded in 4.7% of tests against 1.1% for the next-worst category.
At component level the recurring items are tread depth, registration plates and malfunction indicator lamp — tread depth alone was recorded 181 times.
Mileage matters less than usual here: the 2019 Q8 fails 5.8% of the time in the 0-30k band and 7.0% at 90-120k, a spread of only 1.2 points.
Tyres is the most common advisory, noted on 18.3% of tests — work that passed today but is likely due soon.

What to check before buying a 2019 Q8
The failure pattern for this year is specific enough to inspect against: tyres accounted for 4.7% of tests. Start there.
- Tyres (4.7% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Visibility (1.1% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Emissions & environmental (1.1% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
