Not quite, the aircon is still active up to 5% to provide dried air to the cabin, this is to prevent misting on the windows. clearly, this will be less effective when there is a 5% ceiling but in the main, with single person occupancy and no wet clothes / dogs in the car it should be OK
The descriptive text in the GTR doc is not wholly accurate not for the first time either

Do you have proof, or it's your supposition?
Do you wanna bet?
I can always attach a small light bulb or a LED to pin 29 of BJB and record and show you that the AC compressor's clutch, through RE3 relay, is never energized on ECON...

On FL2 is an externally clutch regulated AC compressor. So it is either ON (100% output) or OFF (0% output).
It isn't, like on other cars (american usually) an internally regulated PWM AC compressor. There you can regulate it from 0 to 100% efficiency.
On FL2, that 0 to 100% is obtained by activating the clutch on a time quantum bassis (so alternatively 100% and 0% output).
But, trust me, on ECON, the FL2's AC clutch is never energized, so no humidity removal based on AC compressor.

Demisting of the windshield, on ECON mode, is made, once the engine is warm, by supplementing hot air to the windshield outlets. But usualy, on ECON, until engine is warm, mist can appear on windshield.

Now Now children - play nicely!

Wading through the the tech sheet I have one question.

If hitting the ECON button turns off the air con why are LR re-labeling it A/C from MY2010 if in fact it turns the Air con off??

There I told you it was confusing!!  There's always a way forward!

2008 Freelander Td4 GS - Stornoway Grey - Now Gone - Sob
2011 Freelander Td4 GS 150 - Rimini Red - in its place - Better x far x 4!!

my MY2010 just has the A/C button

Never pressed as i have my Air Con on all the time summer or winter hot or cold

CHPR did say they had took the ECON button out as it was too confusing  Former Mod/Member, with the most post & Chicken George Arch nemesis

Sorry if I seemed to be too vehement. It was not my intention.
In fact, I believe that the progress can be made from different polemics.
10forcash, sorry if I offended you in any way...

Nick, did your air con become more problematic or did the problem clear itself. Why I ask is, I run my air con year round and just recently the noise that you mentioned in your original post is exactly what i'm experiencing and when I turn the air con off the noise stops instantly.

are you sure its not a loose condenser fan mount ! behind the rad ! only runs when ac is on ! unless engine is very hot.
It took a week for my L/R dealer to realise the fans run when the AC is on, ( total numpties kept telling me the fans were nothing to do with the AC ) or one does and then when the gas pressure rises through lack of cooling 2and 3rd stage fans and speeds come into play

Remember, even if you've got the air con switched on, you need to turn the temperature switch down down to activate it properly. Another member of the failed FL2 clutch/DMF club, twice.

It could be that pegleg but it is very intermittent at the moment and we all know what the dealer will say. I will let it manifest itself a bit more with the bit of summer we are experiencing and having warranty till march 2013.

Interesting to read this thread on noisy aircon. Recently I have noticed mine was getting noisIer, and again noise only heard when aircon fully on, not in"econ" mode. Took mine to an aircon specialist who said it was most likely low gas levels. A quick connect to their system which removed the old gas (just 315g left), checked for leaks and refilled with the correct amount of gas,730g, and my system has gone quiet again...and gets much colder. This regas cost just £40 apparently the gas just seeps out naturally over time and that aircon systems should be serviced and topped up every 18 months but never are.

Thanks XTD5 that gives me another option. Does anybody know if npinks got to the bottom of his aircon problem?

I had a similar problem with my car last year.
After hearing a few opinions I started thinking it was all about a faulty air con compressor. But, nevertheless I went to an independent service in order to check the whole air con installation. They started with gas refilling (they said I might have small holes in the hoses). After refilling guess what, the noise disappeared. And from that point it's all nice and quiet. It seems it had something to do with the pressure (but I'm no expert so I can't explain the process).

I have had the same problem with my aircon but living in South Africa it is much a bigger worry to me as we use the aircon on a daily basis!

I had a new radiator,condenser and intercooler fitted after a slight accedent and had the same whining noise after getting my vehicle back.

I took it to my local dealer who had it regassed- they found that there was only 500grams of gas against the 730 needed. Mine was then filled till 700grams(they asured us that this is sufficient) but the noise still comes back when driving under load e.g. when towing or driving over a mountain pass.

I will have mine filled to 730 grams and hopefully this will sort the problem

Will keep you up to speed.

If you had an accident, then the gas probably escaped forcefully. In the process, it took with it a part of the AC system's oil.
Did they replaced the escaped oil? It's very important to do so, because, during time, lack of oil could lead to compressor failure....

My system did not "leak" after the accident allthough they had to regass the system due to fitting a new condensor. I did not know about the il in the system. Does this run with the gas through the condensor and aircon pump?

I was present when they regassed the system but did not ask about the oil. Will investigate upn going back.

Is there any spec about how much oil needs to be in the system?
