E92 M3 stalled and no power
Y esterday my e92 m3 2011 stalled at a
stoplight after I tried to accelerate. Dash
board lit up with check engine light, abs
malfunction, transmission malfunction. Then
car lost all power. I have random code pop up
in the past but car says all systems ok. Did
some research and most forum say it’s either
the alternator, ecu or junction control box. I
checked the battery and alternator voltage a
few days ago and it was putting out the
correct voltage. The photo attached is the
scan results before the car completely died.
Any idea what could be the actual problem?
Thanks.
Check your Battery.
Same thing happened to me last month. My transmission lagged every gear shift when I clicked the paddles and almost over revved every time. ABS and other lights started lighting up. I Decided to pull over and when I did my car blacked out completely as I pulled in a parking lot. Luckily I had enough roll speed to park it in a space and while I rolled my transmission was clicking. I called a family member to jump start my car and since then, I haven't had problems again. I personally haven't checked or replaced my battery.
I checked the battery and the alternator a day before it died and everything was fine. Just did more research and found that it could be the battery cable that’s connected to the fuse box in glove compartment. They tend to get fried which throws a lot of error codes. There was a recall on that part in the past.
Maybe that explains why my car, since I got it in 2017, at random times the interior has a hint of smell of something burning.
Your going to need this piece to connect to the battery cable behind the fuse box in the glove compartment.
Back of fuse box.
Front of fuse box. You can search on YouTube for this as well.
