X308 AC suddenly stopped blowing cold?

My AC as been an absolute gem this summer, but all of a sudden it appears the clutch is not engaging on the compressor, both fuses in nsf of engine bay are fine, can anyone steer me in the right direction?

Cheers

If there's a lack of pressure in the system, it won't cut in. When was it last checked?

that I don't know... does the fact it was blowing very well and cold just prior make any difference? Wishful thinking but could it be a relay of some sort?

Don't think it's low gas because a warning code is displayed on the AC panel if there's a problem like that. No idea what it could be though.
