Internet Reimport Italy / Country Recoding

I have an Italian reimport XC60. Dealer is 500 km away, and when picking up I didn’t know that there is something to consider here because of the internet. After I found out that the INternet is activated, in which you agree to the terms of use in the menu Privacy Policy, I found out after e-mailing with the provider/telecom that I can’t register because the Fzg. is encoded in Italy (which also becomes clear on the login screen in the car = Italian home page). Info of Telekom: Car has to be uncoded from the country, is not a big deal. Workshop appointment made, on the phone they seemed to know what to do. Car was about 1 hour ago, apparently made software update. Result: still Italian home page, but in addition now error messages (Dring Service SRS Airbag). Workshop thinks that this is normal, with the update I have to drive around for a few days. 300 km later no change. Does anyone have an info about what to tell the workshop what to do???
