Okay folks. I've got a good one for you. I'm currently waiting on a tow truck. While driving the AC stop blowing cold air. That was the only symptom I noticed. Stopped at a red light thinking maybe a shut off restart may help. When I shut off the BMW the engine stopped turning, but all the electrical stuff stayed on. The stereo and HVAC we're still on, as well as all the normal dash lights, however some things aren't correct. For instance, the car says I'm in Drive on the dashboard right now. It's parked and the key is removed. Brake lights are stuck on. Hazard's are working, however they're steady solid on the dashboard. Blinking all around the car otherwise.
