My Secondary Air Injection Pump is screaming on startup too, this is the Unit under the Front Passenger Side Wing next to the Horns.

I read on here, some are saying remove it from the vehicle, I have been told by Steve at Omega Spares that that is not a good idea. Apparently, on start up the unit takes warm air from the exhaust manifold, and uses this info to shut off the cold start procedure, incorporating the EGR, which is part of the engine management process.

No doubt he wants to sell you a replacement? 

Unplug and bin it, it will make no difference to running of the car.

That's "dangle-berries", I'm afraid. Just unplug the pump. It will give you no more bother and make no difference to how the car runs.

As above, the pump isn't really needed at all.
You can disable it by simply removing the fuse.

"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.

It wont have any effect on the Car start-up, especially in winter then, no other systems rely on its function for, say

- idling in traffic when engine gets hot - trying to overheat

- rapid excelleration and gearchange

cheers

No as detailed above, it has zero impact on engine running / performance. You won't even notice a difference when its cold 

[AndysCD]

disconnected mine with no change to running, either hot or cold etc.

I will unplug it then

Great Feedback, thank you.

Even Vauxhall removed it on later cars.

Just to say about comment on Steve at Omega Spares,

Everybody wants to sell you something - Steve does too, but, he wont if you dont want it - his prices are very reasonable - he will still give you an answer to a question, wheather you buy something or not.

Go to him before you go to a breakers or Ebat, his knowledge on Omega's is extensive

On a seperate note,

what unit should I buy to turn off my Airbag Light, also my Wifes Seat has the same problem so I need to buy one - the Omega and the Seat are non-conform OBD11 I think, please advice - I need to get one?

cheers

As proven above though, not quite right on SAI 

Tech2 needed to reset airbag light, prices from OOF and locations here: http://theboy.omegaowners.com/tech2/prices.shtml

[Kevin Wood]

Airbag lights will come on for a variety of reasons, so it really needs diagnosis to find out what part of the system has failed before buying anything, otherwise you'll be wasting your money.

[vauxsky]

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.

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
