What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with indicates excessive fluctuation of brake effort - it accounts for 39% of failed tests on this model.
- Then check less than 1.0 mm thick and tread depth is below minimum requirements of 1.0mm, the next two most common reasons.
- The most common advisory is indicates excessive fluctuation of brake effort (8.9% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 17,239 miles, which is the number to compare any advert against.

|---|---|---|---|
| 3-5 years | 91.92% | 260 | |
| 6-10 years | 91.5% | 412 |
