Did they confirm no issues with the XDrive system? Again, I didn't think I had any issues with my tune, but it wasn't an ESS Tune. However, the error did come up quite often telling me that the AWD system was malfunctioning. Not sure if you depend on this car for the snow, but if you do, you might want to look into further...
