2009 Mercedes-Benz A-Class MOT pass rate and common faults
MOT tests in 2025, published 22 Jun 2026. DVSA publishes a new year each summer.
6,485 Mercedes-Benz A-Class cars first used in 2009 had an MOT in 2025, at about 16 years old, and 59.5% passed first time. That is above the 58.3% for all cars first used in 2009.
The year is when the car was first used, as on its V5C log book, not the model year.

Typical mileage
Recorded mileage at the MOT. A car well above this range has done more work than most; one far below is worth a closer look at its MOT history.

|---|---|---|---|
| 6,479 | 61,900 | 82,300 miles | 104,200 |
