Starter or EWS III What is the problem?

I have a 2003 325xi which will not start. I suspect the starter, but I may have triggered the drive away EWS protection working on the window regulator (lock, unlock, dangit, lock, etc).

How can I tell if the EWS is cutting out the starter circuit due to suspected theft (lock, unlock, etc.)? Is there a way to read the code?

Just prior to working on the window, I noticed that the cranking was getting labored, but the car did start. This strongly points to the solenoid or starter, but I would like to know before diving into that mess!

Also, If I do get in there is it worth cleaning contacts, etc. or better to just replace given the hours of work just to get in there?

Thanks for your ideas and a great site.

Quick update with other relevant information:

When I turn the key, the solenoid does not engage and the starter does not crank. Just nothing. The BMW battery tested out over 700 cold cranking amps with little fade out under load so that is unlikely to be the issue. To be sure, I tried it with another battery which I know to be good and got the same result.

I thought there might be a way to test the starter while it is still on the engine if I can reach the wires, but it seems more definitive if I can somehow read the codes in the EWS to see if it is stopping the starter circuit.

Any thoughts?
