You have to really keep after them. If you continue to have no joy, I suggest calling BMW Customer Service at 800-831-1117.

I have an 04 545i like delje08 above that has been in the shop for 11 of the 30 weeks since I purchased it (and is still in the shop now - dropped it off Feb 11). I was the one who in essence diagnosed it by finding the N62 intermediate lever SIB posted here.
