I need to look at my documentation I got after the work to see if it is new SW version or just a reprogram but they did tell me they would have to reprogram after the work.
No need to wait until monday... just go out to your car and switch off the DSC completely. IF you see the new DSC icon you have the new crappy SW. IF you still have th original yellow circle with the arrow... you have an older SW version.
