whelmic:
I don’t know why the warning is only shown when the card is removed, but they are all the same.Yes a driver should refuse to drive to vehicle if the tacho is out of calibration, as they would be committing a offence by doing so.
But how will the driver know to refuse to drive it if the warning only comes up AFTER or at the time of card removal??
By what said it could be a head fault and it’s booked in
