sometimes it really is just low gas....

i extensively read all the doom and gloom and bad luck postings about aircon , but you got to start somewhere if you dont pay someone to do it for you

so i bought the cheap Halfords STP aircon recharge kit gauge and adapter ,

first you have to find the low pressure side test and filling point , and guess where it is, !! under the left front wheel arch !!
181559

this demonstrated ( following the instructions ) that i had 'Low Gas ' and a recharge would be beneficial
181560


so , again following the instructions, i had already bought a refill bottle of R134a with added oil
181561


i connected to the filling set , ran the engine and proceeded to fill while shaking the bottle like a demented football fan with no games to watch.......( recent history )

and as soon as i started adding the gas i heard the compressor clutch engage and cold air started flowing from the inside vents,
took about 5 minutes in total, the bottle pretty much emptied and i got a pressure reading that i can live with
181562



now, the car is 5 years old, dont know if its ever been gassed before, and only time will tell how much of a result this is

but i got cold air for the time being

Just a daft one, but my local air con specialist only charges £59.99 for a full vac out, clean, leak test, system service and re-gas.

not daft, but it was titled 'DIY'

and its at my convenience, my pace and at my house ( i know there are mobile units ) and no one telling me, oh , its buggered you need to spend more money....

and it added to my skills and knowledge..

just my choice to be honest

Sorry how much was the kit and where from? Sort of job I'd like to have a go at.
Thanks for doing a guide for it.

they can be bought online, ebay or through autoparts dealerships and Halfords,

the bottle was £59 with a £10 return on it ( so £49 ) and i bought a reusable test gauge and filling device for £19

all the gas was used in my case, but this may not always be required if a small 'refill'

Fair play to you BB.

A lot to be said for learning things yourself, having the tools to do the job and the convenience to do it when it suits you.

I thought it was illegal to DIY this. Especially recharging a low system without checking for leaks.

Nice one , the only comment I’d make is if it needs gas, you’ve probably got a leak. Condenser at the front is prime suspect.

ALL refrigerant systems lose between 5% and 10% per annum, and if the PO never even used the system , then this would explain , as the original pressure reading was just below requiring filling ( around 20psi )i would suggest i dont have a ' leak , but annual loss within acceptable limits, as the reading wasn't zero pressure and not indicating an actual leak and an open system to the atmosphere, the on can instructions highlight this scenario and instruct ' do not refill system' ,

and as for ' illegal ' , no its not , it is illegal to knowingly vent banned CFC's into the atmosphere , R134a is not banned ( R12 is as used in my old XJS )

but im not stopping anyone from going to a garage or using a 'professional' to maintain their systems, but there is an on-cost for their knowledge and equipment that is passed to the end user.....rightly so

To balance, I’ve never had to re-gas any of my cars, but take your point if the PO didn’t use climate control the seals could dry out and cause a leak.

Apologies, I wasn't meaning any offence - just quoting recent experience.
Just had the Mrs. 2014 Zafira done, it was down to 185g out of 480 (if I remember right) and works better now.

I've had two cars re-gassed and am probably about to get the third done.. but then again five out of the last six have done/did over 150,000 miles...

The only one that couldn't manage that kind of mileage was a Renault Laguna of circa 2000 build. A car I actually really liked.. apart from the back breaking seat posture...

I've used that kit on a previous car, I think it was my MPS but it worked for me as well.

I had my XF done by a mobile guy (ex Army) we use for doing the big Scania tractor unit and I remember him commenting on how big the capacity is with the XF, apparently more than a RR. I like being able to see it being done.

Our Swift needed done because the wife never uses it (grrrrr) but it had a leak so was going to replace the condenser. The garage tried a bit of sealant first and that did the trick. I was initially worried because I know the coolant radiator sealant basically gunks things up but after reading up on aircon sealant it seems to work differently and doesn't gunk up the whole system.

Thanks for the heads-up Brake buster. Just checked my 2014 Sportbrake, it appears Jaguar have made a modification to the charge point as it is now accessible on the under-bonnet side of the wheel arch, as in the photo

That's the high pressure charge port not the low pressure charge port Carpo:

I used Halfords a couple of years ago to do the recharge but it never quite felt right. It seemed that the air from the left side was slightly coIder than the right. Later learned from a rival company (don't know how true it is) that they use these bottles instead of an ac machine.

Most companies were offering a regas for less than £60 which include a pressure test and vacuum recovery and is lower than what the kit will cost me

In the end I decided to go with Kwik-Fit who are charging £59.99. They also offer a 10% discount for NHS workers. I know that KF have a bad rep, but I have to say that I am very pleased with the results, achieving -3 deg C across the four vents using a laser thermometer.

It's also likely that the temperature reading would be lower using a aircon thermometer. The outside air temperature was 22 degrees. Jaguar manual states "Normal temperature (measured at the center air vent) for a correctly charged and working system is -7°C to -2°C when ambient temperature is 20°C."

They charged the system twice, the first time through the high pressure side only which prompted a complaint. Fair play to them, they stayed open almost an hour past their closing time to get it sorted when I made them aware where the low pressure port was.

In the end, they refused to take any payment from myself, so I got a super cold recharge for free.

I always like to pay for my stuff but hey when you drive a big Jaaag......
