Here is a document I put together from the BMW TIS. I did not know much about your car so I plugged my VIN into the program and this is what I found. By the way, the document is a word attachment. Good luck.
INstalled an aftermarket ViPER car alarm and while I had the panels open I ventured into replacing the ignition switch. Thanks to 'dblmikeusa1' the word doc helped a bundle. The switch wasn't the source of the problem but it's one less thing on the list of possible reasons my 325 has problems starting. Next I tackle the starter... hey DBLMIKEUSA1... any more word docs to help with the starter replace...
