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.

What is a Volkswagen Polo 4 (9N) airbag control unit?
The Volkswagen Polo 4 (9N) airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It monitors sensors, stores crash data, and ensures the proper functioning of all airbag modules in the vehicle, which is crucial for safety.
It is responsible for the precise deployment of the front and side airbags, as well as the seat belt pretensioners. This component forms the brain of the passive safety system.
Typically installed under the center console or driver's seat, it receives signals from crash sensors. These sensors measure acceleration and deceleration in the event of an impact.
Why is the Volkswagen Polo 4 (9N) airbag control unit defective?

After an impact, the control unit stores indelible crash data, which activates the airbag warning light. Such storage completely blocks the airbag system from functioning again.
