Drop links replaced and now the airbag light has come on.
Took the car to a specialist in Electronics as they are the ones with the correct scanners (in this part of Spain) . Apart from main dealers.
He has not told me the code but is saying it is the front passenger airbag.
The concern for me is that the garage is saying they want the car for 4 days and that the whole dashboard has to be removed to ascertain and ultimately replace the the airbag.
I would have thought the circuit could be at least tested without removal of the dash. Maybe at the most just the removal of glovebox.
I am going to have to go to a garage to have this repaired so I am looking for confirmation this garage is giving me correct information.
What does the team think?

Why would working on drop links affect the airbag?

I'd put money on it being the clock spring in the COMM2000 unit or under the seats.

But always first check the battery and do a BSI reset.

I never said it was affecting the airbag issue. I had recently asked a question on here about them. I was really please that had been resolved.
I have done a BSI reset and The under the seat connections have been checked.
The garage is certain it is the passenger airbag or a connection associated with that.
I am asking for some idea on what work needs to be undertaken and if the dash really needs to come out.
How "deep" into the cars "system" can a decent scanner go?

If this is so how would the clock spring begin faulty affect that.

They should be able to check the wiring to passenger airbag with a simulator (aka resistor) in the plug (i'm sure on 307 you can get to dash airbag connector by just removing the glovebox) .

Diagbox/Plant would give a more detailed breakdown on the fault the fault code would be good as we can cross refer that. Passenger Airbag can relate to drivers/passengers as some readers swap sides and dash, side or curtain airbag depended on code

Update.
Late yesterday decided to visit a car breaker to discus what work would be needed to replace the air bag. I have used this guy before and trust him. He immediately said he had never heard of a faulty air bag, not that it is impossible. He did say go to his gargae a few KMs away. I never knew he owned one.
Turned up at the garage and almost immediately the car was hooked up for a scan. Tried several times and the scanner could not ascertain what was wrong as it could not "talk" to the airbag module. I would have to came back the next day( today) and they would try another scan.
The second visit was much more productive. The guy had obviously found a way to scan the car without having to use the Airbag module. This threw up a fault with the passenger side "impact sensor" . I had to tell him where it was. But I only knew that after reading this forum.This was replaced (a yellow one) and rescanned.
The original garage wanted the car for 4 days, strip the dash out and charge around €400 for the pleasure. This repair cost only €75.
I was right not too trust the original garage I visited.
Thank you to those who took time to reply.
