Hi Guys,
I wanted to share my experience from literally the last 2 months, so you can decide whether to do it or not.
I found my airco was performing below standard, it got cold but not ice cold/
So I went to an airco specialist to do a "car airco service".
During the service something went wrong they said they could fill it over 650 grams even though the sticker said 750 grams.
Got the old XF 2010 model 3.0D performance edition.
So after I found my airco did not improve so and they said that even with 650 grams it should get colder and therefore something was wrong.
Due to the fact they messed that service up I went to a specialist.
He said there is an eletronic issue that is causing the "low power / limp mode" the ECU didnt tell the airco to go high power.
He did fill it to 750 grams so he said that is not the issue and everything else seemed ok according to him.
Aside from some odd readings with pressure but he blamed the ECU.
It was 26 degrees that day and my external temp said 18, so he diagnosed it as problem with external temp sensors.
So I got that fixed costed me again a lot of money and guess what, same problem.
So now I am sitting in 35 degrees outside with a non working airco.
All in all, advice is make sure you bring it to someone that knows his stuff.
This has been another nightmare.
Does this might have something to do that I disabled the pre-heater, in the winter my car didnt heat and I disabled it on advice of a fellow member.
But does that pre-heater affect the airco, I would assume not since heater = hot and airco = cold, but I am not sure.
Do know that my preheater caused only cold air, when i disabled it I got hot air again in the winter after 5 minutes but still better to get hot air then none at all.
Now the issue is cold air, it is so hot and the airco blows hot air even on LOW mode.
So sorry to highjack this thread with a question but I guess it is relevant to the airco service question of the OP.
