# Mercedes-Benz 412 MOT reliability: pass rate and common failures | RegFlags

The Mercedes-Benz 412 passed its MOT first time 69% of the time, but from only 80 MOT tests, so treat it as a rough guide. See pass rates by year, common failures and typical mileage.

- First-time MOT pass rate: 69%
- MOT tests analysed: 80 (DVSA anonymised MOT data, 2025)
- Most common failure area: Lights & electrics

These figures come from 80 MOT tests. That's a fairly small number of cars, so they may not be typical of these cars as a whole.
