Hi Guys, so my C30 which is a project car had some airbag issues. I honestl don't know the history of the vehicle, so cannot really focus my attention on single thing in regards to the airbag.

When i purchased, there was a SRS warning light on the dashboard, with typical message Airbag service required. Me and my colleague plugged into diagnostic and it comes up with information that airbag module is faulty.
First and foremost i have ordered airbag module with part number: 3129510 - as per ebay seller, this part belongs to my vehicle (passenger airbag cut off version)
When i lifted the tunel cover it showes that my part number (already fitted) is: 30724045. I have give it a go and plugged this module 3129510 anyway just to try. No luck - Airbag lights still on. Returned module, and purchased correct one this time. Plugged the freshly arrived module to my car, same issue. When i started vehicle, airbag light come off so and message, and then appeared again on the dash few seconds later. Plugged into diagnostic computer - and as before i cannot connect to the airbag module. (unavailable).

Old fitted airbag module:
Product no.: 30724045
00402957A5
Volvo barcode: 007021000759
Temic barcode: F7VB10APN1

New (2nd hand) module which i plugged in recently:
Product no.:30724045
00402957A5
Volvo barcode: 007042600313
Temic barcode: F7V7D26A9R+

As obvious things i have checked both 10A fuses by the passenger footwell.

Any ideas ?
