jom 96 Report post Posted October 20, 2008 So there I was waiting for the lights to change and the engine stopped. Tried to restart, I had dash lights but no cranking. As I was at the front of the queue, some helpful people pushed it around the corner into a parking space. I tried it again - and it started! I suspect that I need to threaten a relay with replacement... Anybody know offhand what the problem is? Details - 97 328i coupe, auto box, Imported.

*Glenn* 854 Report post Posted October 20, 2008 Sounds very much like a battery/power supply problem. You would need to get this checked professionally. If the power supply drops below 10 volts the engine can stop, as the ECU's in the vehicle need a minumum of 10 volts to operate. You could also have an ignition switch issue. Fault codes / live data should identify any issues. Get someone in your area with a brain to check it for you. I'm sure someone on here could lead you in the right direction as far as a reputable repairer in your area. Quote Share this post Link to post Share on other sites

*Glenn* 854 Report post Posted October 20, 2008 dont the cam sensors cause this problem sometimes?? Yes and so do crankshaft position sensors...... but he said it wouldnt crank over as well Quote Share this post Link to post Share on other sites
jom 96 Report post Posted October 22, 2008 Yes and so do crankshaft position sensors...... but he said it wouldnt crank over as well Thanks for the replies, guys. I got it hooked up to diagnostics, and absolutely no fault found. I did discover that when you're at the head of a queue of traffic that's honking at you it's difficult to remember to put it into park.....so that was the unable to crank problem solved (stupidity!) Still don't know why it stopped though. Jo Quote Share this post Link to post Share on other sites

The other thing too... did the guy have a brain and check live data as well ?? Quote Share this post Link to post Share on other sites
