Hi...quick question, does anyone know the location of the webasto auxillary heater (night heater in effect) as i just brought a one owner car (51 plate) and the previous owner didn't know it had one so never been used. so now it blows air into the cabin but it aint hot and it shows up as a fault when i plug code reader in. need to find it to see what fault is....cheers
