The picture
Omega: middle-of-the-pack on first-time pass
Across 1,703 MOT tests, the Omega returns 72.8% first-time pass — below the UK fleet average. The single most-logged Major fail is the strength or continuity of the load bearing. A defective headlamp lens and a corroded brake pipe round out the top three. Average tested mileage sits at 101,189, 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 Omega?
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 Omega 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.
