Could be that your starter failed, like the solenoid that pushes the gear out getting stuck thus no sound not even a click. You could try taking a small hammer or something and tap, hit on the starter solenoid to free it up. If it starts you will know the starter needs to be replace. This test has worked for me in the past.

I had this same problem on my 318, but you can see the starter from above. For both it's located on driver side in back underneath the intake. Looked at my 325 and it's buried. I had to go from under car to replace the starter on my 318, and the only access to the starter at all looks to be from below for the 325, so my suggestion is impractical I suspect for you.
thanks for your suggestion. Its excellent but as you say noy doable because the starter needs to be accessed from below and good luck w/o a lift.
I was told that BMW"s have an EWS chip that is an anti-theft that disaganges
the starting circuit when it fails? Have you ever heard anything about this gizmo?
BMW has everything run by some kind of a subchip or intelligent ckt that reports to the main computer and I understand the starting ckts has two steps to complete (via the computer) before it open the ckt to the starter?
Of course w/o a starting ckt diagram its not possible to say for sure. Does an anybody know where I can get a diagram of this ckt for an 2004 E-46?
I'm pretty sure its the starter system or something to do with the computer and the key that enables or disables the starter ckt.
I guess I will have to tow and take to a shop. Now the problem is finding a shop that has the knowledge and equipment to troubleshoot this.
The EWS system is an anti-theft system. The ignition sends a code to the key, and the key has its own code. If the two codes do not match, the EWS system disables the ignition. Should their be an issue with the EWS system, such as a loss of power, the car may not start. The EWS module is located behind the glovebox. The Bentley Manual has wiring diagrams in it. Not sure if their is a link to the E46 Bentley manual at the top of E46 section or not. If not, i have a PDF copy of it available.
As for the comment of the starter, its possible to fix without a lift, just difficult. Most places actually remove the intake manifold to remove the starter which adds at least 1-2 hours of labour to the total job.
The Intake Manifold is behind the air inbox in a sense. Air goes into the air inbox, and then through the MAF and into the throttle body and then the intake manifold. The manifold takes about 1-2 hours to remove depending on skill level.
I do have a PDF copy of the E46 manual, and i will send you the link to it.
Having the car without the battery for that long wont damage anything. All it does is reset the computer. You will need your radio code though.
Thanks lord that does it for me to see I can't takle the job. It would be an area I have never been to and afraid i would screw things up besides I'm not sure I know all the parts you have mentioned. I would appreciate the link though. Is it a BMW doc or a third party?
