It could well be the bearing behind the clutch mechanism, mine went bad after it was soaked in water.... Errrr..... For four hours😬 it's held on by a circlip once the clutch is removed. Watch out for the shim if you remove it!!! Unfortunately I broke the circlip end of the bearing shaft on my compressor 🥴it's been loctited on for over a year now🤭
 
Do you have the regassing slip - did they put PAG oil in as part of the refill? Hopefully yes, but otherwise the compressor is running dry. Where did your AC lose pressure from originally?
 
If you turn the clutch by hand a few turns can you hear it? Any play there?
on that theme... energise the clutch with a 9V battery, engine off...can you manually move the clutch at all (ie could the clutch be slipping) maybe just check the clutch gap with a feeler gauge, for good measure
 
Yes they put PAG in. Will try the other suggestions soon. At moment it seems to have quietened down & AC cools nicely !!
 
Top right corner of the condenser seems to be a favorite place for pin hole leaks.
On one of mine, a recharge would last 2 weeks, the vac test at the garage showed nothing. The dye in the recharge located the pin hole.
Same here - leak at top right corner of condenser. New condenser, problem solved.
(That's top right when viewed from driver's seat, as per standard JLR procedure.)
 
Found the AC Gas leak on my P38. Looks like clutch needs doing as well, so new compressor complete with clutch required.

Might do that as well, but not looking forward to bumper off.

Trip to Bedford EuroCarParts with tools required !! My son can get staff pricing, so I can fit them & get Gas recharge in one trip.
 
I try to spray some wd40 or similar the day before trying to remove something... Good luck?

On a different AC note:
Will a pressure test adequately check a system? Mine was tested and refilled hence assume no leaks. However AC does not cool :-( Cold at compressor/pipe in engine bay, and compressor just cycles on/off every few minutes.

Is there a good idiots guide on the AC system to troubleshoot?
