What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with not working - it accounts for 40% of failed tests on this model.
- Then check excessively stiff or notchy and tread depth is below minimum requirements of 1.0mm, the next two most common reasons.
- The most common advisory is excessively stiff or notchy (5.5% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 4,511 miles, which is the number to compare any advert against.
Pass rate by age
