I put my problem and my previous story in, maybe you have some clues where the workshop should look (I have no idea about it myself).
So I have my V8 before about. 6 years bought and when bought the climate did not cool any more, so it was filled up and everything was good, cooled as on the first day.
Then after about 2-3 years the cooling power went away, I did not miss the climate and did not take care of it any more, thought it is empty again.
But after I sweated in the car a little too often last year, it should be different this year.
So to the workshop of my trust and I said: Please check if the climate works and fill it up...
He did, too, and his statement was going to climate! Since we had 13 degrees outside at the time, I accepted it so and drove from the yard.
This weekend it was time: Saturday 30 degrees , 200 kilometers highway and the climate unfortunately does not cool at all..
What I still noticed, the additional fan didn't work either, it always did that the years before, I know that because I switched on the engine with the traffic jam so that the engine does not go over 100 degrees.. that actually means that the climate has no pressure, but it was definitely filled up ...
I hope you understood that and maybe even a few solutions.
I want to tear next weekend with it 1400 kilometers , a climate would be very valuable
