Was just out at the car just now, renault said they took all my plugs out and said they were fine, took the pencil coils out and to me I don't think anyone has been near them, still white corrosion marks on the coils etc no sign of any de grease or cleaning etc mmm I smell a rat! I don't have a deep enough bar to get to the plugs but tomorrow I will and check them out. Anyone got part no for plugs?
