Probably worth checking that you have the right MID for the Car first, in case its been swoped at some point in its life for missing pixels etc.

Press and hold both buttons on the stalk for a few seconds should bring up a table on the MID, the table can be cross referenced as to what the MID has been programmed for, ie, Engine, Gearbox, Wheel type etc. fairly sure the table info is on this site somewhere.
Agreed. My 3.0 saloon was pretty accurate (within a couple of %) and the 3.2 I currently have is accurate to within the same sort of leeway... Pretty good IMHO, especially as most trip computers have a habit of inaccurate readings in the direction of making it seem better ::)

Most Omega OBC seem to be very accurate so you need to check you have the correctly calibrated display

I've checked the MID configuration and got the following numbers:
084 1
24060
I haven't been able to find whether this is correct for my car although I did find a key to the numbers on this site.

I am pretty sure that it is the right unit for the car because I have lots of garage bills from the previous owner, going back to when the car was 2 years old. I can see that he spent quite a bit on maintaining it with the local Vauxhall dealer. None of the bills mention anything that looks like a MID. So I think that this is the original unit fitted during manufacture.

Thanks, I had managed to find that page but it doesn't cover my model as the table only goes to 1998 and doesn't have the 2.6 - mine is a 2003 V6 2.6. Frustrating.
