I have already replaced the wiring harness, fuel pressure regulator, fuel pump relay and had the connections from the relay to ecm cleanded. The local mercedes dealer forgot to put the gromits in when he replaced the wiring harness! I have recently received the name of another shop in town and will try them. I could tell it really PO these guys that I was even asking about the OVP. Even our local Mercedes Dealership has mentioned nothing about this failure. They all suggest that I wait untill the problem gets worse. By waiting will I cause major problems down the road? Should I replace it now?
