It has ben over 2 years that I am facing the following problem with my 970 Hybrid Panamera

All started with "hybrid fault " on the panel , cutting the operation of the a/c (dramatic in hot weather during summertime)

To be more speciofic I observed the following combination of problems related to the hybrid ops:

α) Cutting the opearation of the a/c with or without the  "Hybrid Fault" yellow msg on the panel (may appear later)

b) Cutting the ops of the electric motor AND the a/c with or without the  "Hybrd fault" msg on the panel (may appear later) 

c) No a/c, operation however of the electric motor  with or without the "Hybrid Fault" msg on the panel which may appear later

I visited a number of Porsche dealers. Initially nobody had a clue what was the cause. They only changed the a/c coolant  and for a short period of time the problem appeared as solved. But days later  the problem appeared again. I changed the  a / c compresor wih a second handone. After the change  everything waso .k for couple of months. Then gradually the problem appeared again.

In the meantime I noticed the following: 

α)  Under hot weather the msg "hybrid fault" appears after a short period of driving time. Under cool wather (<20c) it is o.k with no problem unless driving in heavy traffic. No problem driving under cool weather at the highway,

β) I have the feeling that the a/c compressor is overheated but I am not sure if this heat is normal or not

I checked the battery cells, the orange cables, the coolant and the collant system . No problem.

They are now telling me to change the a/c compressor again, (Cost of new in GR appx 5.500 euro ). I wonder however why the same problem happens with 2 different compressors and if it is not the compressor but something else. 

Any assistance pls.?
