    Hi everyone, Was taking my 05 M3 vert out for a drive today. Wouldn't say I was driving super aggressively but wasn't a stroll around the park either. Oil temp was about 210. I accelerated fairly hard, almost to redline, and all of a sudden the red battery light turned on solid. Immediately...

    I've been having a rather occasional problem (only happened twice so far) with my M3. The DSC, Oil, EML, and Battery lights come on and limp mode ensues. It then starts to have trouble maintaining idle. This last time, the engine died. If I turn the car off and back on, it runs fine. I didn't...
