WOW, I found it help.I am a member of the iatn website. I am having problem with a 1994 M-B C280 with 106000kms {wifes car!]. It doesnt start after a 15 min drive. A wait of 2-3 min.s is needed before it starts. It also has the ocaisonal stall waiting at a traffic light. The other problem is the turn signal sometimes doesnt work. sometimes if i play with delay wipers ,it works. I replaced the switch with no luck. The rest of the car is perfect. Please help me make my wife happy again!

The motronic(fuel & ignition) computer requires a good steady voltage supply, & the relay that supplies the voltage has a high failure rate. M.B. suggests that the early version relay be replaced whenever any car has the type problems you are having! The relay is called "OVERVOLTAGE RELAY".
