I just heard back from the dealer,
They were able to reproduce the problem ( squealing screeching noise on idle and coming off throttle, and stumbling idle and sometimes car dying)
I thought thank god , they actually found it.. Im not imagining it
they said they got some strange ( they did not elaborate) codes off the vanos system ... and they are going to keep it over the holiday , ( hooray for loaner cars).
The combination of VANOS codes that they dont know about , and the screeching/squealing noise makes me very nervous... thank god for a warranty!
Anybody interested in wagering a guess what the heck is going on
