With regard to the ABS, TC and speedo, this is a well known about problem on this forum and many people have had it unfortunately.

It points to the ABS ECU being defective. (The speed signal goes through this, so ABS, TC, speedo, speed sensitive power steering, trip computer etc will not work) The problem appears to start intermittently then get worse until total failure.

I have heard Vx charge up to £900 to fix.

DIY methods include refurbishment of your own part from a range of companies (which many people including me think is best), or obtaining a 2nd hand part, but this needs to have the same part number and be off the same engine size/year etc. Cost of refurb in the region of £130.

There is a guide in the maintenance section telling you how to get the ABS ECU off. It's not straightforward but doable.
HTH

PS

Forgot to mention, some lucky people have manage to solve the problem by cleaning their ABS sensors on the rear wheels which of course is a whole lot easier!

I don't know much at all about auto electrics, but have you got a lose connection/eartch connection somewhere to cause the car to cut out?

Welcome to the forum aswell!

As Geoff says - abs ecu fault, most likely. As  for the cutting out - I would suspect either ICV (idle control valve) needs a clean, or possibly crank sensor. Do the paperclip test and if it shows a code19 then you need a crank sensor. Hth. :y

Update you profile with your location, there are travelling mechanics here who could do it for you. Otherwise depending on how handy you are, set a day aside to take it off and another day to refit :'(

Thanks for the replys. Thats a massive help!

I ve got a friend who does all my work, ex vauxhall mechanic. I ll set him on to it! Will try the rear ABS sensors first and give them a good clean. Fingers crossed!

What age is the car?  The ABS ECU fault tends to affect 1998 and later...

Also, many "Vauxhall Trained Mechanics" do not have the skills to work on cars - but if he is a known, trusted chap, all well and good :y

What changed for the '98 onwards cars?
Is the ECU from a different manufacturer than previously, or a different revision?

Excuse me butting in please psycho sport, I'm just curious.

I think ... but not certain .. that is when it changed from a 3 channel ABS system to the present 4 channel one .. so a completely different ECU and hydraulic control...

An expert will pass by and correct me shortly ... no doubt ...  :)

I believe it changed from 3 to 4 channel but not 1998 but late 97. Mine has had two go in my long tenure. :y

i don't know if this will help you but some users here in romania managed to repair their abs ecu on vectra b and it works like a charm. i don't know if its the same as the one on the omega but if you are handy with the tools you can try to do it.

this is the original link but is in romanian

you can try to translate it with google language tools

I would be very interested to see what's in that thread Boditza, but it seems to need a login before it is available.

Can you please copy/paste any pictures from it that show approximately what is involved?   :)

Is the repair anything like what's described here ?

yes.. its precisely like that(i was logged and didn't thought it is needed).. the main thing is to redo all the weldings there and it will work but verry important, at least for me, is to know your way around with electrics
