Starter is not working

starter failure have tested most likely gear failure

It is very prudent and sensible of you to have concerns about this.

I would check with BMW service if that is an issue with that system and, in particular, whether or not it is an indication that the there might be an impending failure. Unless there is some kind of back up key that can enable you to operate the ignition and starter motor to start the car if the starter button fails, such a failure will leave you stranded. On some vehicles with this starter button system, failure of the starter button definitely will leave you with no other way of starting the car..

Sounds like you have an ignition circuit failure.
Check the Fuses in the engine compartment and the starter relay.

could have faulty starter or starter solenoid.hook test light make you a test light with longer wires and 12 volt bulb with socket go junk yard find good bulb with socket.hook test light to starter and see if test light lights up if so your starter or starter solenoid has a open winding. if test light dont light up could have blowed fuse to transmission neutral switch or neutral switch could be bad.try to start vechicle in neutral if vechicle starts your transmission neutral switch out of adjustment or neutral switch faulty check make sure wires going to neutral switch is damaged.

In older cars, the natural wear and tear on a vehicle can lead to ignition switch failure. If the switch is failing, you will probably not hear any clicks from the main relay, which fires the ignition. Check the behavior of the dashboard lights if your vehicle stalls. Alternatively, when the key is first turned to position two, the oil light, brake light, charge light and other warning lights will not function. You can try a test to check the integrity of the ignition switch by turning the ignition key to the 'start' position. As soon as it tries to start let go of the key. Allow it to snap back to the 'run' position and note warning lights. If they go out as the switch snaps back then the switch is faulty. if faulty it will not let power through to the starter to start car. check all fuses first. but sounds like switch.

This definetly sounds like the starter motor has gone.

This is Indicative of a STARTER FAILURE (TRY) Smacking the Starter with a Hammer SOUNDS CRUDE But IS VERY IFECTIVE at Times when the Starter is on its LAST LEG. Replace Starter

Make sure you have a good connection between your starter and battery cable to the battery. Also check your ground connection from the battery. Your battery is the source of power that kicks the starter to turn. So just follow the battery cables to be sure they are clean and have a good connection.

Today 11-12-08 my 2003 H2 Hummer would not start. Checked battery it ischarged. Cables tight. Tried to start with portable booster pak. No go. Tridto jump start with my wife's Suburban. Still no go.
When I turn the switch I hear a single click and that is it. No engine turning over. While trying to start with key the headlights go out. Out of ideas, Will take to Chevy garage in am. Will post solution.
