Arona Fr Red Edition Ecotsi: a strong MOT record by UK norms

Across 1,712 MOT tests, the Arona Fr Red Edition Ecotsi returns 89.3% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is excessive fluctuation in brake effort through each wheel. Brake pads worn below 1.5 mm and a seriously damaged tyre round out the top three. Average tested mileage sits at 23,247, 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 Arona FR Red Edition Ecotsi?

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 Arona FR Red Edition Ecotsi 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.
