My air con isn't working very well. When turned off the pressure as read by my plug in diagnostic tool is about 9. When engaged it goes up very slightly to about 9.5 ( no indication of units). Would anybody with an L322 and the diagnostics mind checking theirs? I believe it is the compressor which is faulty.

Are you sure it just doesn't need re-gassed? Got - 2017 SDV8 Autobiography in Loire Blue

Is the passenger side vents colder than the driver side.

Mine was like this. Halford regas 44 quid just sorted it

could be the condenser leaking, its right at the front and liable to get hit by stones and road debris... ... - .- -.

I had it regassed, it appears to have pressure, it just doesn't change much when turned on. That said I am not sure what the pressure should be. Hence my request for somebody with a working one to check.

its a no-brainer to get it regassed, because, (at least they used to) they guarantee that if it doesn't get colder by about 4 degress. its free. also, if you need a condenser, because of no gas pressure, and leak etc. they are about £90 on ebay. if you need the pump, they are on ebay for about £225 new both not the hardest things to change, but I did mine and removed water rad at same time. the gas also has a lube in it.
its a good idea, to leak test all the joints as soon as you get it back from aircon guy, so you can fairy liquid and paintbrush the joints and see any leaks. obviously you wont see it when its all gone. mine is also a 2002 v8. and they use the same pump as the x5

It did have a leaky condenser, which was changed. I then had it regassed. It held the vacuum but they had trouble regassing it and afterwards it wasn't getting colder so I wasn't charged. I have got a spare compressor but want to check the pressures with known good ones before paying to have it changed. I can't think what else it can be.

I did a post 18 months ago and posted my pressure values.

I have found it, it looks like you were seeing about 15-16 when turned on, but still no values for when it was off. Thanks very much though, half way there.

MC

is your pump clutch engaging? you might see it spin up when turned on. with a torch placed. -mind your hands on the belt though.

Yes it is engaging, the pressure does change slightly and it can be seen to be engaging.

if I remember correctly, I put 35lb in mine with the engine doing about 1100 RPM RR 2005 4.4 petrol

So about 7kg not much needed but how much to start with and was the compressor going before you did it?

Sorry I didn’t make that very clear.
I connect up the gauge ect, start the engine, turned on the gas just a little and let it slowly flow in to the system.
I only use the blue gauge and connector fitting
Once there is enough pressure the compressor should start.
With the engine running at about 1100rpm, I let the pressure build up to 35psi.
I am no expert but I have been doing it like that on all my vehicles for a number of years.
