Put $33.00 of premium(93 Octane) before we left to go to dinner 45 minutes away. Got to the restaurant, ate, came back out. Started the car and it immediately dropped RPM's to about 600 and started shaking, could physically feel it inside the car. The car then just shut off. Thought maybe it was just an intermitent problem and tried starting it again, and it did the same thing.
I had a couple days before all this happened brought our manual into the house, so I didn't have access to try and reset the ECU, so I disconnected the negative battery terminal for about a minute and reconnected. It still did the same thing(started,hesitated, then died).
The car is 45 minuted away as I had to get our neighbors to come pick myself,wife and kids up, so I can't really access and try and troubleshoot. I am trying to get ideas as to what it might be if it's something quick and easy that I can try before I WALK to the BMW dealership, yes, I said walk. The dealership is a mere 200 yards down the street from where the car is broke down. I have to go back down there tomorrow to go to the doctor, so I can try a couple things, maybe reset the ECU(not sure how?????), or as my last resort, have the dealership come pick it up under our extended warranty. What do the late night BMW finatics think it might be?
