Yes, there is a dual pressure switch which disables the compressor relay if there's not enough pressure in the system so make sure it has pressure in the first place
Can you read pressures in the system with Lynx? Would tell if no gas, or if you have gas, a sensor problem. (Bit of course this may not show if a sensor is duff) Could then only be confirmed by physical checking for gas.
If it has lost gas where’s it gone and why?

Well, update on mine and maybe linked in a way to gjmac s problem.
Although I have now got a cheep multimeter, my dearest wife spotted a 2nd hand Hawkeye locally. Ended up buying this because it was coded for the D2 same as ours.
I was able to check air con relay and also clutch; both functioned normally. Seems to have power at every point from heater switches to relay and clutch.
Speaking to a landy mechanic who is doing my exhaust head gasket, he thinks the gas hasn't been pressurised correctly by the radiator garage i went to. That garage told me to have a electrical fault diagnostic done by their friend in the next unit. They didnt want me around whilst they did the test but said a regas was free afterwards with the unit next door. Now it all sounds a bit fishy, because i cant see anything wrong anywhere. My landy chap said discos can be prone to loosing pressure from a leaky pipe in the front behind the grill, but said a proper pressure check should have picked this up. I don't think this was done when it was regassed. Think I will get my landy chap to check it properly, I'm sure it will work afterwards, even if a pressure sensor is needed.
