2001 Mercedes Benz 270ml Repair Question
Ml270 glow plug stay on even i changed the plugs and the relay
you have to have a prob with the harness. start at the relay with a schematic you will find you have power going to a circuit when no power is supposed to be there. this prob could be a faulty ignition switch sending power to the wrong circuits this is an electronic switch located on top side of your steering coloumn.
