What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with missing - it accounts for 38.3% of failed tests on this model.
- Then check excessively loose and the less effective brake control does not achieve an efficiency of 25%, the next two most common reasons.
- The most common advisory is excessively loose (9.5% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 8,139 miles, which is the number to compare any advert against.
