What to check before the MOT

Built from this model's own failure record, not general advice.

  • Start with not working on dipped beam - it accounts for 31.4% of failed tests on this model.
  • Then check less than 1.0 mm thick and missing, the next two most common reasons.
  • Age matters here: 86.18% of 3-5 year old examples pass, against 75% at 6-10 years - a gap of 11.2 points.
  • The most common advisory is less than 1.0 mm thick (8.4% of all tests) - not a failure, but money you will spend sooner or later.
  • Average recorded mileage at test is 9,376 miles, which is the number to compare any advert against.

Pass rate by age

A single pass rate hides the most useful thing in this data: how the same model behaves at three years old and at fifteen.
