Just replaced the instrument cluster and Bsi unit on my c3 and before doing so the mileage was 39,900 +/- a bit. and now it displays 100,000 My car goes for the mot soon and i wonder what mileage they will put down? Its going to be bad if they put the 100,000 down as the mileage when its not the correct mileage. Where is the mileage stored? The BSI unit or the instrument cluster? Maybe i can get a unit with a nearer mileage but which one do i go for? The BSI unit or another instrument cluster? Thanks
