Drove a couple hundred miles today and when I got home and tried to crank it to go back out again the car would not start. I have what looks to be a full charge on my battery as the lights are full brightness, but I get nothing when I turn the key. I know this sounds dumb but I never change out anything on my bimmer, I always have my mechanic do stuff. Could this be a starter problem or something else perhaps. The car does not even turn over slightly as with a weak battery, and no clicking noises, just a deafening silence. Thanks for all your help, and if anyone could provide instructions on how to change it out I would be very appreciative.
