The picture
Er: a strong MOT record by UK norms
Across 1,104 MOT tests, the Er returns 85.2% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is tyre tread under the limit. A missing rear reflector and a non-functioning shock absorber round out the top three. Average tested mileage sits at 15,267, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Buying or keeping an ER?
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own an ER and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
