HELP we have a 2012 dualogic qubo. A week ago it wouldn’t select a gear and we noticed a puddle under the car on passenger side. This happened when we noticed the air bag passenger side had been deactivated and we reactivated it. Car has been with a mechanic who cannot seem to find what the problem is and thinks it may be an electrical fault. I’ve contacted an auto electrician who won’t look at it with it being the gearbox as this is something they do not do. Has anyone else had the same issue and how did you fix it
