As far as I can see you haven’t said what year your car is. If you put the info in your profile it’s useful for other members when trying to answer queries.
I agree with FighterPilot. Don’t attempt to fill it yourself. You almost certainly have a leak. Very likely to be either a seal or the condenser itself if it’s an earlier car. A good test is to set it to cold, switch on sync and check the centre vents. If you can feel different temperatures either side, it’s probably low on gas. My 2015 car had the condenser changed just before the warranty finished. 2 previous years it went in blowing warm air and was pressure tested but no leaks found. Each time they just refilled it. The 3rd time I insisted they sort it and eventually, I think as a last resort, they replaced the condenser. That fixed it. Take it to a specialist and see what they say.

Well I have been doing a bit of research !

There are loads of faults listed under different headings.

Air Conditioning Blowing Hot Air. I found 3 members with similar problems warm air coming from drivers central vent. Posted 20 July 2018.

Faulty Air Conditioning. 5 members 27 May 2017.


Stone Chip. 8 members. 28 Nov 2017. Similar problem but claimed to be stone damage .

All of these seem to be similar problems affecting cars built up to 2017 . I have heard that there were quality issues with cars built in this period . Mine is a XE 20 t
2016.
These faults were found just by a quick search on Google . How many more with similar problems are yet to be discovered but JLR should have a pretty good idea.
We tend to use our car with the air conditioning running most of the time as we are aware that seals need lubricating . The idea that the vehicles should be run frequently doesn't seem very likely . How often do you walk into a car showroom to hear the sound of engines ticking over ? Cars must spend a period of stagnation at some time prior to being sold .
As I have said our 10 year old Kia Venga doesn't have any problems with its air conditioning. I have used it for comparison. I have discovered that the low pressure pipes on my XE do not get cold as they do on our Kia. There is hardly any difference between the temperature with the air con on blowing air through the vents than it being off. The right hand side vent is definitely warmer than the left .
I will try to contact the salesman today. As I have said previously, I have found the sales department more helpful than the service people . We think that were were told that our car had a 1 year warranty when we bought it . If not I will ask about a good will gesture as I was pressurised into having a service done which I was totally against . I can sense that my blood pressure may be about to explore but we will see .

Classic sign of low gas on the XE. Sync on, set to cold, mine was blowing 15c on one side and 4c on the other. Yours probably has a very small leak, either seals or in the condenser itself. which is very often undetectable even with the dealer supposedly sophisticated pressure testing gear. I think from memory the acceptable figure for normal loss is about 3% per year but as you have no way of knowing the history of the car, it's possible that the previous owner ignored it and it could be down 15 to 20% over 5 years. A top up will probably sort it for a while in any event.
Unfortunately it's no good comparing an older car using the older gas. They last forever.
It does seem that most XE aircon problems were with 2015/2016 cars and the number of posts on the subject nearly all relate to those years. Some dealers did try it on when owners complained. They tried to make out aircon was not covered under warranty but that is certainly not true of the Jaguar warranty although of course third party warranties may be different.

Thanks .
I have just been out to my car to try an Idea of mine . The temperature outside is 25 C so inside it was a bit hotter ! I put the air con on but it was unbearable ! It's no wonder I thought it was hot on Tuesday . The air coming out of the right hand vents is hot !
I thought that I would try to see if I could match the temperature coming out of the vents by raising that on the passenger's side until they matched . This didn't work as the passenger side remained cool .
I think there is something else amok with the system . It would seem as though the vent is almost coming directly from the heater matrix .

It's possible that one of the stepper motors that move flaps within the HVAC system to direct airflow for heating or cooling has failed. This is not unknown as a problem, although differences in temperature between the LH and RH vents in the XE have been reported as fixed in the past by merely re-gassing the system - though it puzzles me why lack of cooling capacity should affect one side of the HVAC system more than the other side.

Thanks .
I've been reading other threads where people have had a similar problem had it re gassed and had it return a while later .
The old slider and cable operated heating systems were far more reliable .

Low pressure in the system. A regas will sort it as they check for leaks. That is exactly how mine was back in Feb. A regas sorted it and over the past few days it is perfect.

Yes they were, and I still have such a troublefree system on my other car - a 1993 Cavalier V6. Trouble is sliders and cables can't offer auto climate control and are entirely dependent on the driver (or passenger) making adjustments to keep the temperature in the car as required.
Nevertheless these manual adjustments were never a problem for me and the now almost universal stepper motor systems do introduce what might be considered as an unnecessary level of complexity and potential to fail.
The Cavalier also enabled the upper air vents to blow cool air to the face while the footwell vents blew warm air. This is a good way to stay warm but not feel drowsy, but I've never been able to completely reproduce it on the more modern HVAC systems.

I had the earlier model Cavalier CD 1800 hatchback . Lovely car, it had a pull back sliding roof and power steering .

Maybe my case will help someone. My Jag is 2016 and I had problem with aircon. When I go to aircon mechanic they diagnose leakage of gas. They where not sure from where directly so they changed radiator and made again leakage test with good result. After one week I hade the same problem - no gas. They disassemble all parts connected with air condition. Problem was on oring seal. They said me that in their opinion factory wrongly assembled seal on “low pressure part” of aircon. After this everything is working perfect. Maybe it will help someone in the future.
