My wife loves this car but the price of a new EA was more expensive than a round trip flight to Stuttgart to dope slap a German engineer for using self destructing wiring and who knows what else. Anyway, for the last couple of weeks there has been a hot no-start condition. About every three days after the car has set about an hour, it cranks but won't start. Sometimes letting it sit for another half hour, it will start, some times it takes two hours. The fuel pump at the tank is getting power during the no-start but the injectors are not firing. Could this be an OVP relay? The OVP fuse is okay. What is the part number of the newer relay. Thanks in advance for any help.
