I'm getting a G65 High pressure sensor error. I've reset it twice but it still comes back.

The symptoms that I have is that the climate control always stays on ECON mode.

I was quoted a price of $80 +tax for the sensor from Audi.

I have the same problem, no cold air. I had the A/C charged last year and worked but was empty 10 months later. I have taken the car to a garage and been told the pressure sensor is leaking.
I have replaced my self the pressure sensor, took it to a shop recharged the A/C but still not working.

The scan revealed this (United Kingdom car):

1 Fault Found:
00256 - A/C Pressure/Temperature Sensor (G395)
002 - Lower Limit Exceeded - Intermittent
Freeze Frame:
Fault Status: 00100010
Fault Priority: 3
Fault Frequency: 30
Reset counter: 25
Mileage: 253116 km
Time Indication: 0
Date: 2016.12.29
Time: 16:22:15

With new sensor installed and no leaks something is preventing the compressor to engage. Any suggestions? Do I need to clear the DTC's?

Thanks

How did you determine that middle switch/pulse was open? What test did you run?
