VOSA MOT Special Notice
Where an earlier recorded mileage is higher than a later one this could be caused by, for example, a speedometer replacement or a mistake by the tester at the time of recording the reading.
When an error is made in recording the current test mileage this can be rectified within seven days of the test by issuing a replacement certificate. After seven days it will not be possible to rectify an error in the current test mileage reading.
Please note that if there is an error in one or more of the previous mileage readings then this cannot be changed.
