I'm in France at holiday and I stopped to wash the car with a pressure wash (by hand). I simply walked around the car spraying the entire vehicle down, nothing unusual like opening the bonnet. When I finished the engine would not start and there were multiple error messages after pressing th Start button (all of them, as far as I could tell!) other electrics seemed to work (radio, sat nav, lights). Mechanic checked that it wasn't a dead battery, eventually managed to clear most of the faults but disconnecting battery and holding the pos and neg contacts together to 'reset' the system according to him. All faults cleared apart from a check engine error, so even though car seemed drivable, LR roadside assistance advised the car be taken to a dealer to review the fault. LR assistance were brilliant, but I'm a little p***ed off that washing this three month old car would trigger such a serious set of faults. I imagine water from the pressure wash got somewhere it shouldn't, but I honestly didn't do anything that I haven't seen the London car washers do countless times. So, anyway, I'll update this board when I know what the LR dealer says, but in the meantime if anyone has had a similar problem with this or other LR modes your advice would be appreciated. Also, as a warning to others- avoid pressure washing the car!
