This Happened after my car got stuck in snow and i was trying to get out of it. My dad chained my car to his car to help me out.i got out of the snow but the next day it wont move but it starts.
I am able to start my car but it will not move when i put it on a gear. on 2002 BMW 325Ci
Mine did this due to an air leak by the air intake. It was an easy fix and inexpensive. The only low cost fix on this car.
