It depends on rpm, I did an up hill test in 3rd gear with rpm in the high 2000s with the ACC menu up, ambient 83F, #3-4 increased about 4 degrees, #5 about 8(from the low 40s to 51-52) and #7 dropped to about 9-10 from 15-17. So Id have to say this seems to happen mostly above 3K rpm.
I dont have gauges, but will ask my mech to run some tests when the car is in for inspection in the next week or so.
Thanks for all the input....hoping the compressor is not showing signs of its age-which is unknown to me.
