Top advice on the phone, my control unit/Fiat 500 arrived there on a Wednesday, Friday came the message: Defect found and successfully fixed, by Monday I already had it in the mail. The airbag light came on, the workshop's diagnostic device could not establish any communication. Assumption: airbag control unit defective. On the phone I was told that this is a known defect with the Fiat 500, so sent it off and immediately after reinstalling the problem was solved. I would give 10 stars if I could. Many thanks. Price-wise absolutely fair ; unthinkable that you'd have to pay well over 1000 Euro for a new part with new coding etc.
