Airbag?

Hello people has someone’s experience with the RAID retrofit adapter?Unfortunately, it was too fast to be installed in the B4 (without problems) and mounted a 30s sports steering wheel but now the TÜV has shown me that I am not allowed to drive with the PROCON-TEN system (which mine has). Does anyone have a tip what I can do? PS: I have already made a request at RAID; if I call on the phone it is no information only by e-mail. But no one has registered for the mail since 3weeks!
