What to check before the MOT

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

Start with not working - it accounts for 40.7% of failed tests on this model.
Then check too low and has a serious fluid leak, the next two most common reasons.
Age matters here: 90.21% of 6-10 year old examples pass, against 80.79% at 16+ years - a gap of 9.4 points.
The most common advisory is less than 1.0 mm thick (6.1% of all tests) - not a failure, but money you will spend sooner or later.
Average recorded mileage at test is 23,659 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.

Age at test	Pass rate	Tests
6-10 years	90.21%	143
11-15 years	85.71%	49
16+ years	80.79%	151

Most common advisories
