2020 Audi Sq7 — MOT failures & pass rate
Across 771 MOT tests, the 2020 Audi Sq7 recorded a 90.4% pass rate. That is effectively the same as all cars of a similar age (9.3% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in tyres, brakes and lighting & signalling.
What the MOT record shows
One area stands out: tyres, recorded in 7.3% of tests against 1.2% for the next-worst category.
At component level the recurring items are tread depth, registration plates and brake pads — tread depth alone was recorded 17 times.
Mileage matters less than usual here: the 2020 Sq7 fails 9.2% of the time in the 0-30k band and 9.6% at 60-90k, a spread of only 0.4 points.
Tyres is the most common advisory, noted on 19.3% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 13.0% in 2023 to 8.5% in 2025, as the worst-kept examples leave the fleet.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 19.3% | 149 |
| 2 | Brakes | 9.1% | 70 |

| 6 | Lighting & signalling | 0.8% | 6 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 240 | 9.2% |
| 30-60k | 418 | 9.6% |
| 60-90k | 104 | 9.6% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2023 | 276 | 13.0% |
| 2024 | 235 | 6.4% |
| 2025 | 247 | 8.5% |
What to check before buying a 2020 Sq7
The failure pattern for this year is specific enough to inspect against: tyres accounted for 7.3% of tests. Start there.
- Tyres (7.3% 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.
- Brakes (1.2% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Lighting & signalling (1.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
