Hi All

 

Got the above air bag fault the other day after a long drive.  It can be cleared by the durametric but turns on with the next ignition cycle, so it's permanent.

I did read about boxsters needing a new harness because of this, but my local porsche mech says it's probably the connection to the airbag in the door (inside the door panel) or the airbag itself, however I'd like to check the door harness connection point by the passenger's kick panel first, which is the easiest thing to do before I tear the door off - but not sure how to get in there yet.

RHD 2005 997.1 C2S in New zealand, so no salt and dry garages, no moisture issues etc.

Well, I put a 3ohm resistor in place of the air bag and the light goes out and I can clear the code, so I guess the airbag needs to be replaced...

Loren - does a new (or second hand) airbag need to be coded to the car?  I have a durametric pro to clear codes etc.

 

No coding to the car - just clear the fault codes.
