2019 Audi S6 — MOT failures & pass rate
451 MOT tests on the 2019 Audi S6 are in this dataset, and 94.5% of them passed. All cars of a similar age fail 10.1% of the time, so this is 4.6pp better than the group it competes with. Failures cluster in tyres, other defects and visibility.
What the MOT record shows
No single area dominates — tyres (3.8%) and other defects (0.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, registration plates and malfunction indicator lamp — tread depth alone was recorded 9 times.
Condition tracks the odometer closely. Failures run at 3.7% in the 0-30k band and 9.2% in the 60-90k band, a 5.5-point spread — more than double.
Tyres is the most common advisory, noted on 15.5% of tests — work that passed today but is likely due soon.

| 0-30k | 136 | 3.7% |
| 30-60k | 229 | 5.7% |
| 60-90k | 65 | 9.2% |
Failure rate by age
Trend over time

What to check before buying a 2019 S6
The failure pattern for this year is specific enough to inspect against: tyres accounted for 3.8% of tests. Start there.
- Tyres (3.8% 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.
- Other defects (0.9% of tests): Miscellaneous items not in the main categories. Typical repair: varies.
- Visibility (0.9% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
