Engine Size: 2.0 L
Refrigerant Type: R134a
Ambient Temp: 88F
Pressure Low: 25
Pressure High: 88
Country of Origin: United States
Static Pressure with "cold" car - 100 psi
After running for a few minutes:
Is the high side port after the receiver-drier? If so, could be blocked receiver drier. Hard to otherwise explain how high side could ever be lower than static pressure.
Also it's likely badly undercharged.
The variable compressor regulates the low side to 25 psi over a wide range of operating conditions. So it looks like that feature is working OK. It is a common problem for those compressors to get stuck at minimum displacement but yours seems alright for now. Really in order to make a diagnosis of a variable system you have to start with an evacuate and charge by weight.

She's happy for the time being, now the "leak watch" begins.
