Ds3 seats belts issue

[Simon22]

Hi All
I am new to forum and I can't find help online. My wife hit the post with her ds3 and both front seatbelts went off and now passenger side is pooled in tight and drivers one is stack half way out. Airbags did not went off.I have scanned the car and I am getting only one fault code F6A0 triggering of pretensioners.
Now my question is do I need only two new seatbelts or I also need to replace airbag control module and crash impact sensor as well. Please help.
Many thanks

Yes you will need the ECU replaced and the Pre-tensioning buckles, straps and stalks. I suggest you get it looked at properly as there may also be other requirements of the system that need replacing, but the above and the ECU for sure.

Thank you, I will look now pl for parts codes and organize replacements
