Also have air con problems on my Discovery 4, ran pressure test and there is a leak in the hose from the condenser - the part from Landrover is £195 plus the vat alone!!

I have used the products above and they are OK for a temporary fix that will get you through a season. The top up gas works well on a solid system that has just gradually lost pressure, but if you have enough of a leak to need the stop leak product, you will eventually need to get it fixed.
To do a refill job properly though you need to ensure the right amount of gas/liquid in the system. Pressure is a blunt way of checking this as it is greatly affected by temperature, and to a lesser extent by air pressure and humidity. That means without very specialist tools you will need to completely drain the system (vacuum pump and storage tank) and then add the right weight of coolant.

Clutch taken off donor using 10mm socket and oil filter clamp.
Small washer retained with copper grease.
Fitted plate washer and bolt to existing compressor.
Works due to rubber bush flexing.
Will look for suitable washer to reinstate donor then keep as a spare.
Fitted gas valve thing in orange (high) started off no spinning. Turned on climate spinning.
Gas pressure dropped to too low.
Ended up adding gas to 30psi.
Total cost £110

Il be digging into my 04 D2's aircon when I get back from work, as the high pressure side is reading way above what it should be. Well done on your repair
