Hi there, I've got an octy II with the dreaded seat airbag fault, checked all connectors under seat etc but to no avail. Has anybody tried this resistor fix and succeeded? I've tried 3.3 ohm and 4.7 as described in other blogs but the light still returns? And please don't give me the safety lecture I understand what the implications are. Hope somebody can help!

I think you need less resistance - 2 ohms? Do you get fault codes come up, as they will say resistance too high, until its not too high.

Hi thanks for the quick reply! It usually just moans about the igniter (can't remember exact words) but I will try a 2 ohm resistor this week and post my findings!

Where are you fitting the resistor? If there's a wiring problem then you will still get the fault.

You need to scan the car and then post the code.

I'm planning on fitting the resistor where the cable plugs under the plastic cover in the body, I've had the whole seat cable out and checked it with a multimeter so I'm at a bit of a loose end really! Don't really want to fork out for a new seat airbag the cars done 210k it's just not viable.

if the wiring fault is before where you are fitting the resistor then it will make no difference, you may need to fit it at the airbag controller end. Assuming of course that its not the airbag controller itself thats faulty. You could buy a secondhand one of those and try swapping that first as failure is not unheard of.

Just to clear this one up, turned out to be the yellow and brown wires in the rubber housing between the A pillar and door, bit of solder and heat shrink tubing, vag com to knock the light back off, job done!

hi what size resistor did you use as my airbag light has just come on

Didn't use a resistor after it turned out to be a broken wire in the rubber shield that connects the door to the A pillar

Interesting that this was solved by fixing broken cables to the door.

 

My understanding was that cables to the door do not lead to the side airbag itself -which is in the seat-, and therefore I assumed that a fault code pinpointing the igniter would also indicate a fault in the seat (or between the seat and the controller, e.g. that infamous yellow plug/connector).

 

Does anyone know if the igniter is actually in the door?

Crash sensor will be the thing in the door.

Yes, that is what I thought too.

 

But user @tdiestate says about the fault code that "it usually just moans about the igniter (can't remember exact words)". And the he solved it by fixing wiring to the door.
