Car wont start, but all lights work....Theres no turn over sounds at all, car simply wont even budge, but all signs of a bad battery are no there, all electrical things work.

SOUND LIKE FAULTY STARTER SOLENOID OR STARTER MAKE SURE BATTERY CABLES AND BATTERY POST TIGHT CLEAN TURN OFF RADIO FIRST BEFORE REMOVING BATTERY CABLES. TO KEEP FROM LOSING CODE. USE A MEMORY SAVER IN CIGARETTE LIGHTER BEFORE REMOVING BATTERY CABLE.BMW WARNING YOU BECAUSE YOU SHUT DOWN PCM VECHICLE HAS TO BE TOWED IN AND REPROGRAMED .IF ALL IS GOOD YOU COULD HAVE PROBLEM IN ELECTRONIC IMMOBILIZER CONTROL OR FAULT IN THE TRANSMISSION CONTROL UNIT.

First check the battery especially with BMW if its low there is a safety feature which will prevent it from starting even though the light may still be working. If the battery is ok check fuzes and the. The starter motor. Hope this helps. Jim...

Check the battery like this:
Turn on the headlights, then try to start the car.
If the headlights do not dim or go out, then the battery is likely ok.
Check that the battery cable plus post, goes to the starter, Minus post to a good ground, like the engine.
If wiring is ok, then look at the starter solenoid for a good connection.
Problem is most likely the Solenoid or starting relay, whichever the car uses.
Hope this helps.
