What did you do with your Range Rover today

More than likely need a new condenser/dryer if its been open to the elements.

Pro's try and pull a vacuum if It can and holds then its recharged, if it fails to hold a vacuum then the source of the leak has to be identified.

Otherwise it won't hold R134a..

Don't full it with air for godsake, you have a Low pressure side and a Hi pressure side, the fill always goes through the low press side.
 
I've got the new condenser and new drier ready to fit.
The way i see it, any oil in the system is unknown, could be full of dye from a previous leak test etc, at best sludgy and manky

Some A/C places add dye regardless of whether there is a leak or not, it makes finding any future issues easier..
To flush the system the correct way is to remove the refrigerant hose from both the high and low sides of the condenser. Fresh fluid will be poured into the high-side inlet on the condenser. Subsequently "the only time Air is introduced" compressed air will be added into the high-side, forcing the shít from the outlet hole in the condenser, until any and all contaminants are removed from the system.

Also seen a pressure valve that should be removed, might be on the bulkhead somewhere, could be gummed up and not working. Worth checking before doing any work i think

hi

don’t know if this helps u, my ac hadnt worked for ages , I used air to fill the system up first to find the leaks , know ur suppose to use nitrogen , but I was going to fit a new dryer and air had been in the system because it had been leaking for ages

Found my leaks using soapy water , was on the condensor , so replaced that and a new dryer , then used one of the oil extractors to pull a vacuum , everything was fine

then took it to a company who done the vacuum test yet again and also pressurised it , as sometimes systems can leak under pressure and not a vacuum or vice versa

after they proved it wasnt leaking they re filled it with the correct amount of PAG oil and R134 and all sorted out

I done all the tests on the low side using an ac gauge set

of course they may need to add dye if they can’t see the leak

hope that helps
