UKPassats

I'm sure this has been done to death but i'm having issues with the A/C on my Climatronic system. I have run a scan on VCDS and the only fault is re circulation flap which has since been replaced. I have conducted basic settings, been into measuring blocks and the compressor shut down codes are 0 for on and 6 for econ mode and its got 7 bar pressure regardless of whether its on or off (regassed last year). Has anyone got any pointers for me on this? I have had a search and there is very little specific to the Passat B6.

thanks in advance
