[QUOTE="Russie, post: 14803, member: 4537"] This happened to me on Saturday afternoon. Being a rookie in BMW, I was trying to jump start another car (Kia Spectra) using my E36 318i. Connected the cables to the other car, revved the E36, cranked the Spectra but could not start. Then suddenly, my E36's engine just died off. Tried starting my E36 but it just wouldn't want to start. Then I went to take out the (-) terminal at the car battery. Left it disconnected for about 15 minutes, hoping the ECU would be reset and everything would be ok. Connected everything back and turned the key to start the engine, I heard cranking and then engine managed to start but was shaking badly. Out of a sudden, the engine died off again and I could smell petrol from the exhaust pipe and some black smoke.Thinking I have fried the ECU, I called up the mechanic and told him the situation, he was afraid that the following might have happened:-1) Fried the ECU2) Fried the battery cable (the positive cable - red in color with a fuse inside)Sunday afternoon, the mechanic came over to check with GT1... after almost 1 hour, finally, managed to reset the ECU and EWS. Yes, the short circuit affected the EWS too. Man...this was a whole big lesson to me. Never jump start any other car again :) So, to you guys out there who wanna do this, better think twice and do not take the risk of frying the ECU. [/QUOTE]
