BMW M3 Competition MOT pass rate & common failures
1,187 MOT tests on the BMW M3 Competition (2010–2023) give it a 94.7% pass rate. All cars of a similar age fail 8.6% of the time, so this is 3.3pp better than the group it competes with. Its most common failure areas are tyres, other defects and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (3.2%) and other defects (0.8%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are registration plates, tread depth and headlamp aim — registration plates alone was recorded 17 times.
Tyres is the most common advisory, noted on 11.5% of tests — work that passed today but is likely due soon.

| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 838 | 4.4% |
| 30-60k | 332 | 7.2% |

What to check before buying a BMW M3 Competition
- Tyres (3.2% 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 (0.8% of tests): Miscellaneous items not in the main categories. Typical repair: varies.
- Lighting & signalling (0.7% 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.
