Thanks for that I've just had the aircon regassed. In my previous cars I could set the climate at 22 degrees and it was nice and comfortable. I would have expected that it would be similar in this, at 22 degrees I feel like I'm in an oven!

How do I check for leaks etc? Cheers.

iirc Vauxhall recommend to to set it to 21 and leave like that all year round (not in Eco mode). They claim it is the ideal room temperature or something like that.

However 21 on the Omega is indeed quite warm, and I said before the thing seems to have a mind of its own anyway, so i wouldn't worry too much about it. If you get chilly air when the system is on LO, and warm air when it is on HI, then you should be happy with it... everything in between the LO and HI doesn't really count.

And yes, TB upgraded my aircon ECU with his Tech2 (at least we both think he did)

22 would be uncomfortable warm in either of ours, but everyone has there own prefered temp.

In maint guides there is a picture of vac pipe layouts, may be worth following this, there have been instances of incorrect routing causing speed sensitive aircon!

Would that be cold air when driving and warm air when stood still by any chance??

iirc Aircon changed at 4000 rpm - rear multiram and hbv vacuum pipes swapped.

So that's what the "Small knobby thing" is.  I've been wondering for ages and kept forgeting to ask.
