Seat Toledo airbag fault

[Adambart84]

Hi guys, I have a 2005 Seat Toledo which has had an airbag light on since I got it, there is a note in the servive book saying its an airbag squib fault and it needs replaced. So I have replaced the airbag and tried deleting the fault but cannot, I have read many posts about issues with the under seat wiring and although there only really is one cable I have tried disconnecting/reconnecting it and wiggling etc.

A few people have suggested removing the plug and soldering or crimping the wires but im not convinced that is going to work, is there anything else I could try? Or should I just bite the bullet and take it to an auto spark?

Thanks for any help offered☺
