What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with missing - it accounts for 47.7% of failed tests on this model.
- Then check not working and tread depth is below minimum requirements of 1.0mm, the next two most common reasons.
- The most common advisory is tread depth is below minimum requirements of 1.0mm (6.9% of all tests) - not a failure, but money you will spend sooner or later.
