What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with tread depth is below minimum requirements of 1.0mm - it accounts for 33.3% of failed tests on this model.
- Then check remains on when the brakes are released and less than 1.0 mm thick, the next two most common reasons.
- The most common advisory is excessively stiff or notchy (5.1% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 28,764 miles, which is the number to compare any advert against.
