I’ve recently got my Omega back on the road and so far I’ve had both seat air bags replay for no reason!

First was the drivers side I was moving cars on the drive, jumped out n shut the door only to the first latch, didn’t slam. When I got back the cars full of smoke n a airbag sticking out of the seat!

A few days later just driving back from petrol station and a massive bang, the passengers seat has deployed aswell! No one in it so shouldn’t have gone off anyway.

I gingerly drive the car back expecting more airbags and disconnected the battery then the airbag ecu. I’m hoping this will stop any more goin off but I can’t really see anything wrong with the ecu.

Has anyone else ever had this before?

Nope, never seen that (outside of a real accident).

IIRC, the seat ones are only triggered by the door sensors, so has anyone been pissing around in the doors, either around the sensor, or the riveted plate that the sensor uses?

If driving, its probably possible bumps might set up, especially if the car is rock hard.

It hapened to me few years back on my 2.0 estate...Just leaned the door on first click and went upstairs. Side airbag deployed when I got back.

I assumed that would be the senor in the door to triger them but nothing has been touched on the doors and I was on smooth bit of road while driving. Nothing’s changed suspension wise in the last few thousand miles so can’t go blaming that really.

I’ll see if I can get into the ecu later, I was wondering if my water leak behind the dash has got into the ecu but it’s no where near that area!

Did you ever find out why or fix the problem?

[Doctor Gollum]

Any buggering about on the seat wiring/wrong seats etc?

I could possibly understand that, if the door was banging/vibrating on the catch.

Doubt it'll be wet, unless you've been pour drinks over it.

If you can read the ECU, it will tell you why, but I suspect the door sensor has triggered it.

I thought that, once the ECU has deployed an airbag, it effectively logged a code and then bricked itself? I.E. it's designed to be a single-use device.
The fact that it's popped an airbag on two occasions makes me wonder if it did actually get triggered by the ECU deliberately.

is it this part Airbag shock sensor GM09173205 or GM09173929 /both/all(more numbers listed) just seem to be 2 pins. could it be a lose connection ?

[Doctor Gollum]

A short in the loom might do it...

Have the pretensioners fired?

I believe that's for frontal impacts, when the main airbags/pretensioners fire.

I get a feeling that side impacts don't do this...  ...but not brave enough to test

I've a dented spare driver door here (just swapped for un-dented version)
I will strip it out in the next few weeks and see what sensors /goodies are inside soon and report back
(unlesss blinded by airbag dust ,unable to see computer screen  )
