[s-cars] A/C problems

[Chewy]

This year its getting bad.

My 95 S6 compressor shuts down for a min or so when temp is around 80+
and maybe sun is out.
I check head codes and all I get is steady center flap code meaning
nothing I think.
I have changed multifunction sensor and even toped off freon.
If I'm moving over some 30mph or so ac works great if im in traffic
just rolling ac is on and off useless

Any I deal would help
thnx in advance
