Thanks Paul that was my thinking exactly!Your airbag ECU is not active whilst there are lights up and potential crash data. You can drive it, it makes no difference if the ECU is not, but it would be questionable should anything happen whether you would be insured. You know what insurance companies are like, don't give them an excuse. The guy I use to clear them turns them round the same day, so it's three days and you have it back.
