2006 BMW M6 — MOT failures & pass rate
Across 603 MOT tests, the 2006 BMW M6 recorded an 87.4% pass rate. Against coupes & convertibles of a similar age (21.9% fail rate), the 2006 M6 comes out 9.3pp better. Failures cluster in lighting & signalling, tyres and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (4.3%) and tyres (3.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rigid brake pipes, washers and wipers — rigid brake pipes alone was recorded 15 times.
A 120-150k example is materially riskier than a 30-60k one: 12.8% versus 7.5%.
Advisories point at the next bill rather than this one: brakes was flagged on 23.2% of tests without failing them.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Brakes | 23.2% | 140 |
| 2 | Tyres | 22.7% | 137 |
| 3 | Suspension | 11.9% | 72 |
| 4 | Emissions & environmental | 5.5% | 33 |
| 5 | Lighting & signalling | 3.6% | 22 |
| 6 | Other defects | 3.1% | 19 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 30-60k | 147 | 7.5% |
| 60-90k | 275 | 11.6% |
| 90-120k | 125 | 20.8% |
| 120-150k | 39 | 12.8% |
Failure rate by age

What to check before buying a 2006 M6
On a 2006 M6, lighting & signalling is what the MOT record says goes wrong most — it appeared in 4.3% of tests. Check these areas before you commit.
- Lighting & signalling (4.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (3.6% 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 (3.5% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
