The oil is called pag oil and you are meant to add a certain amount when recharging the system and even more if changing certain parts ie compressor etc
50ml for a compressor rings a bell?

The slam panel label tells you oil amounts these days I think.
Compressor change requires oil adding.
I suspect most cheap places don't add oil.
Most can stay in the compressor, but if the leak area looks oily you know U lost some

Thks , that’s interesting
Great info as I will at least be able to now ensure that it’s done, wonder how they check there’s enough in the system, unless of course the oil is all removed when they do a vaccum test so know how much to add into the system

Yes they are meant to, but when we had a new guy start at my previous job we were talking about a/c work and he had never added pag oil in the several years he had been doing the job!

Many thks , see ATS have some offers of doing a full recharge for around £60
But will see if there’s an AC specialist local or maybe a mobile tech, so that after I’ve sorted the leak out will vacuum the system out / recharge , so it’s all done correctly
Blimey, we’re there many complaining of noisy compressor then

That is the problem. You just don't know how much oil there is left in there. So experance is used.
Another good reasons not to use tyre companies to do AC fault finding.
There are plenty of mobile guys who don't know what they are doing either. Franchised, with bare minimum training

Thks pete , won’t bother with a mobile company but a local specialist
Most Appreciated for the great info
Plus found some interesting info ref the dryer , as mines empty looks as though it will be advisable to replace the dryer

Useful info Glad they have thought about it and given some guide lines as to what to add after specific work done. Really good of them.
The dryer is there to protect the compressor. I personally would only replace the dryer if a new compressor has been fitted. As it would be there to protect the new compressor over its life.
Little point fitting a dyer at this point if you aren't confident where the leak is.
If you were to find a massive hole in one of the hoses (for example) where moisture could have got in over a number of years, that would also be a good reason to replace the dryer.
But for you, at this early stage of trying to find the leak, would be fairly pointless and could shorten the usefulness of the new dryer if more work is required to find the leak

Good that it may be useful to others and indeed they’ve added the section when parts are replaced ref the extra oil
Reading where the condenser is suppose to be a common issue but always like to go through a system step by step and only replace parts if I can prove there leaking , could be something simple like leaking O rings to indeed the condenser
If at the end of resolving the leaks I couldn’t see me getting away with just replacing the dryer , seen it in boilers where the material is an aluminium and becomes pitted so never seals again properly without replacing the main component , that in this instance being the condenser
Will just see what I find and go from there
Thks again as always for the sound advice

The dryer comes with a new condenser
If it's an HSE, it's either the rear AC pipes or condenser leaking

Quick update with mine....
As expected the official Land Rover Extended Warranty ( total example of an oxymoron if there was one) has determined that my rear pipes had corroded and therefore the warranty is null and void..
I obviously challenged this as nowhere in the terms and conditions does it say it won’t cover it through corrosion... their reply was the t’s and c’s state ‘discolouration alteration and deforming of parts due to aging’. It makes a total mockery of any warranty when they start being colourful with their interpretation...as the old adage states it’s not worth the paper it’s written on!
Somewhat annoying as this is the exact reason I spend an absolute fortune on an official OEM warranty in the first place...
What the latest feedback from the warranty company is that it is a design fault....the pipe has allegedly failed due to water being retained in the sponge insulation covering!
Anyway the short story is the dealer wants £1100 (plus vat) to replace the aircon lines as standard or to bypass it and fit the short section £700!
An email complaint has gone in but I anticipate it being a waste of time... the likely result is I will pick my car up without working aircon and I won’t be renewing any warranty with Land Rover Extended Warraties!
