I think it's a 4+ hr. job to R&R, so you want to eliminate simpler possibilities first.

Of reports on this forum that had similar symptoms, the end result has been a few surprising things, such as:

- an engine control sensor gone bad and locked out the start protocol

- transponder in the key failed

- battery tested good still unable to energize the starter (more likely if continuous clicks)

It's worth checking Fuse #14 to see if that has blown as it controls the immobilizer and/or the EWS.

Failed X3 starter motors are not unheard of but not too common.

If the warm weather had anything to do with it, maybe the battery electrolyte evaporated a bit.
Battery testing is not a very exact science. I'd charge it up fully and try again before anything else.
Thanks for the help, in relation to your several points, i have now got the battery disconnected and being trickle charged overnight, but when i had road service he did try to jump start without success to eliminate battery issue/s, either way ill know tomorrow for sure when its charged and reconnected.

I have two keys with the transponders, last week i went to get in the car and the doors wouldn't open and i had to get in the boot as only that worked, after slicing open the plastic cover i found the small clicker had snapped off hence im now using my spare key, which has been working without issue all week, also i did try the old key to start as well but no luck.


- an engine control sensor gone bad and locked out the start protocol....................Not sure how i go about finding this out, code reader didnt show any faults but i have only a simple eBay one.

See: http://www.trapdoor.demon.co.uk/bmwx................I will check that out as a couple of other people mentioned it could be retlated to the immobilizer.
