[size=12]Hi guys, a little help required if possible. Just bought a CDX Auto 2.2 2001 facelift model a couple of weeks ago. I've done approximately 900 miles in it so far so its now sat on around 81,000 miles. MOT'd 3 weeks ago with no advisaries.
The emission control light came on whilst I was on the road for about 50 miles or so and remained illuminated for a further 200 miles. The light then went out and came on again the following day and remained on for a further 200 miles or so. The vehicle was taken to the Vauxhall Garage and they said it was probably the Lambda sensor which would cost around £160 to get fixed.
After reading a few of your threads on here I came across the Paper clip and foot pedal test. I know now that neither of these work on my model, however, before I knew this, I did the foot pedal test and the Emission Control Light went out.
Can anyone point me in the right direction as what to do next because I'm going round in circles. :-/[/size]

The light going out when you did the pedal trick is pure coincidence .. nowt else. !!!!
The pedal trick (paperclip trick on the 2.5) can ONLY read the codes and not reset the light.
Either the fault condition has dropped below the preset threshold or the bulb has blown !! Bulb can be checked on startup ... if it still works the fault condition has gone, temporarily.
To find out what it was needs putting on a code reader. Stick your location in your profile, someone who has one may live nearby ..... if you are lucky :)
BTW ... "Hello" and Welcome to OOF .. :)

Thanks for the super fast response.
The light still works so it must be an intermittent fault. I think I'll stay away from main dealer for now and maybe save some cash.

Not for certain .. :( Some faults put the light on instantly, others "build up" slowly and only put the light on when a preset "threshold" is reached. The fault will be readable by a suitable code reader as they are stored as "pending" codes... once the light it on they have reached "active" status. If the value drops below the threshold the light goes out
If you have the known pre-cat problem building up code 0420 it is possible the "error" is presently "around" the threshold and is changing just enough. Only way to know, properly, is a decent code read.

Many thanks for that, just need to find someone with a code reader locally. I've had a look on ebay at a couple suitable for Vauxhall/Opel but for the Omega-B priced at £29.99 but very unsure as to what I'm buying.

Dirt cheap ones off ebay are not particularly good or useable. Many rely on the use of a laptop and software, which can be pretty dodgy. Ebay "versions " of standalone ones are often cheap chinese copies.
Fow what its worth .. and just my opinion ... the Maxscan GS500 or the newer Maxscan MS509

are very good value for money. have the GS500 and am very pleased with it. The cost is the same as one visit to a Vx dealer... and I've used mine lots, and not just on my own Omega, but several members cars as well as the wifes shopping trollley (clit).
It has paid for itself several times over.
