My good ol' 320i has been giving me a really irritating issue lately.
I have no idea what is causing it, so maybe you have
Sometimes when starting, Click ignition to #1, Then #2, perfectly fine, electrics seem fine, but once i Turn it to #3 (Start) it shuts off, Leaving no 12v Power in the car, even if i take the key out and turn it to #2, Nothing.
My only remedy currently is un-bolting my battery, letting it drain, then re-attaching it (Always Remedies the issue.)
Thanks in advance.
