Thanks again a8_tech.
If I understand you correctly the zug level 824 corresponds to version 4220 and the zug level 921 is 5150?

What functions will be updated in the Tuner and Interfacebox with 824 and 921?
Will it make any noticeable improvement to my car or can I just happily stick with zug level 731?

Kind Regards
