It is a failure with new rules, TheBoy based in Brackley, Northants would be your closest OOF member with Tech2.

[Kevin Wood]

In this case I know why, I replaced the doors on my Omega as they were rotten (98-S) and put some facelift ones on, so I had to disconnect the Side Impact sensors, so they just need re-setting.

If you followed the normal precaution of not turning on the ignition when working on the airbag system then it wouldn't have turned the light on, so I reckon there might be an issue with the sensors in the new doors - or the wiring isn't compatible.

As for the Seat, It has been on since we had the car - 10 years, its the switch under the seat, but I want to turn them off permanant.

As I beleive the MOT is now a failure on Airbag Lights

The airbag system must go through its' normal sequence when the ignition is switched on for an MOT pass - so light must come on and go off to indicate the system has no faults. You can't, therefore, just disable the whole system.

we are drifting a bit here, I think Kevin, you are closer to me, you have Tech 2

When I did the doors, the ignition was not turned on, the loom had to be disconected one way or another to put it into the new doors.

But, I still would like a recomendation on a Unit to buy.

Going back to the SAI issue for a moment.

Yes, it can be disabled by removing the fuse - I 100% agree with that. But you are then carting around several pounds of excess weight and pipework that sometimes gets in the way when working down the front of the engine.

That can all be removed - but there is a bit of making good to do though:

1) There is a vacuum line which connects to a valve. Make sure you seal the vacuum line pipe when removing the valve otherwise you will have a vacuum leak.

2) Leave the electrical valve in place. If it's removed then it will bring on the ECU light. It can physically be tied up somewhere close by - but it's presence is checked by the ECU.

3) The two stainless steel pipes from the manifolds need to be capped off. Luckily these are jointed to the SAI pipework with long rubber joints and circular clips. The way I sealed mine was to get a short length of 15mm copper pipe with an end cap soldered to one end. Measure how far down the rubber tube the pipe needs to be and then cut to length to get a tidy fit without the end cap sticking too far forward. Use a circular "Pipeslice" to get a nice straight edge to the cut - this lessens the chance of a leak. Finally, use the pipe clip from the SAI pipe you previously  removed. If necessary you can use a jubilee clip.

I've done this to a couple of V6s now with no probs.

"Dangle Berries and Unplug it and Bin It"

These are radical fixing ideas, why did VX fit it on there, whats the technical reason for having it, before I decide to remove it.

cheers

It was put there to keep greenies happy, its purpose is to reduce exhaust emissions when engine was cold only.

Is that not a good thing then? Does it not save a little fuel if it ends the cold running setup sooner? (I don't know that is just a question)

It makes no difference to fuel consumption during warmup whatsoever. All it does is to blow air down the exhaust pipes to help the catalytic converters to warm up quicker.

Also remember a 2.2 does not have SAI

I disconnected mine and didnt realise the pipes had to be blocked , went for a run .... it erm sounded a bit loud  looking at this i think ill try the disconnection again  Thanks for info Links Robert 

[TheBoy]

You'll find my SAI pump and all associated gubbins in Ardley landfill site.

Any emissions savings by getting cats hotter quicker are outweighed by lugging that weight around.

Well thats one thing I don't have to worry about at least then! :-)

I think I might be keeping mine if you have to do all this - any pictures of this procedure?

cheers

No - it has to come out when doing a cambelt change - so went that bit further and never put it back in again.
