Car runs great now! Here is the info below from the service order:

Hi, and thanks for sharing your experience.
So, your VTG module was defected as well. Had you got any trouble codes in iDrive regarding VTG failure? Did your dealer scan your car at the beginning and practically found the VTGE trouble code? Or it was a hidden trouble code that need some special tool to detect?
I may conclude that the VTG (which is an electrical motor and should be monitored by DME/TCS) can be failed without throwing any trouble codein the iDrive!! Is that true?
