I am sorry that this is my first post on the forum... but i have to get to the point...
Car shuts down while driving approximately once every 24 hours so far (1 week so far)
today on my way to work it did,
I uploaded a video of what's happening when i turn the key, since maybe i can't exactly explain due to my english fail, it just won't ignite. 20130829 091813 - YouTube
last time it did this a battery reset fixed it, but this time I tried to disconnect the Battery for 10 minutes, then 20 minutes, and still won't run.
So after trying with the battery and nothing... i opened the fuel pump, removed both of the electrical cables on it, and plugged them back in, and voila, car running again.
This might be that or that's just pure luck, i now have 2 options to get the car running again, either the fuel pump plugs, or just waiting half an hour for it to run again, i can't really narrow it down so far...
I have disconnected the alarm immobilizer, and mechanically checked the car , and analyzed it in a BMW electrician shop through a computer, no fault codes appeared.
What could this be?
My mechanic (who's not an electrician) is recommending me to replace the car computer and the Crank Sensor.
