failed dme?!
Okay so a few days ago i was driving my 2011 135i dct when the red battery light flipped on. i kept driving until i had to get off my exit. as i was coming to a stop a Christmas tree of lights appeared and the car started sputtering. the car then died and would not start again. tried jumping it and did not start. so i just replaced my alternator, a new battery,(all oem and coded) and a fuel pump relay. car still does not start i scanned the codes and this is what came up. no wires seem to be loose or disconnected. ugh hoping someone can help before i bring it to the dealership and have to have the dme replaced.

I couldn't begin to tell you if this is your problem, but regarding your specific question, I've seen it fairly regularly with audio amplifiers. Corrosion or a bad connection will cause errors, but if you hit it with enough juice, the current will arc across a gap or make its way through a corroded connection. Low power systems may be affected (DME), while high power systems (starters) aren't.

Distribution box interesting.
I guess I need to take a closer look at that. I always assumed power went from battery, made a pit stop at the fuse box under glove box, up into engine bay white box by passenger side, lug for jumping, over to starter and DME. |
