Looking for some advice about replacing a drivers side curtain airbag on my 2007 A4 Avant 2.0 tdi. The wiring loom to the airbag module was damaged by a small fire setting the drivers curtain airbag off, I have fully repaired the wiring loom/fire damage and fitted a replacement airbag but haven't connected the wiring yet. I'm worried about triggering the airbag again so if someone could point me in the right direction that would be a great help. I have a replacement airbag module from a non damaged vehicle if mine is cooked. Do I need to replace the side impact sensor? Do I reset the module before connecting the new airbag? Thanks.
