What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with not working - it accounts for 33.9% of failed tests on this model.
- Then check missing and does not illuminate by the operation of both brake controls, the next two most common reasons.
- The most common advisory is excessively loose (7.2% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 19,658 miles, which is the number to compare any advert against.
