What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with has a serious fluid leak - it accounts for 20.3% of failed tests on this model.
- Then check not working and insecure, the next two most common reasons.
- The most common advisory is is so short that the brake cannot be readily applied (9.3% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 12,494 miles, which is the number to compare any advert against.
Pass rate by age
A single pass rate hides the most useful thing in this data: how the same model behaves at three years old and at fifteen.
| Age at test | Pass rate | Tests | |
|---|---|---|---|
| 6-10 years | 71.52% | 158 | |
| 11-15 years | 73.91% | 92 | |
| 16+ years | 71.05% | 76 |

| 10 | The less effective brake control does not achieve an efficiency of 25% | 8.1% | 6 |
Most common advisories

| 3 | Is bent and the brake cannot be readily applied | 7.5% | 25 | |
| 4 | Tread depth is below minimum requirements of 1.0mm | 6% | 20 | |
| 5 | Tread not clearly visible | 5.7% | 19 | |
| 6 | Has a major leak of exhaust gases | 4.2% | 14 | |
| 7 | Corroded so that its cross sectional area is reduced and seriously weakened | 3.6% | 12 | |
| 8 | Less than 1.0 mm thick | 3.3% | 11 | |
