Re: Ds5 No A/C even after replacing pressure sensor
I have Lexia/Diagbox, so have not needed to look for alternative systems, but someone else should be able to help with that.

Re: Ds5 No A/C even after replacing pressure sensor
after diagnosing the car today at the dealer next result came out.
error code P0532(signal pressure sensor) short circuit to ground or open circuit. Now I have to measure everything. any advice would be really apreciated. they gave me all the wiring diagrams but still very challenging.

AC FINALLY WORKING
2 connectors where not making proper contact. Both from pressure sensor and compressor.

Well done, great to find and cure the problem. 
I used to be indecisive, now I'm not so sure!
I used to ride on two wheels, but now I need all four!

Re: Ds5 No A/C even after replacing pressure sensor
This seems identical to what I am experiencing now.
I ve recently changed my compressor . I thought my original one was gone, it only had a burnt clutch coil. Anyway...
My AC now is totally stopped , But it was behaving just like what you described. Even the 1.3 volts reading, and the pressure sensor code "shorted to ground":
My clutch would sometimes kick in, but the fan would not turn, and the ac not cool. i changed the resistor of the fan and no change. I cleared the codes as much as possible with the faplite app.
I suspect now the variable solenoid from the compressor may be the culprit.
I saw your conclusion, and your issue was only plugs poorly connected.
Was there any more detail to it? Did you replace anything? why it was marking 1.3 volts. etc.
I appreciate any help.

Re: Ds5 No A/C even after replacing pressure sensor
sorry for the late reply. maybe you already fixed your issue.
Assuming your pressure is fine and you have no leakage the readings of 1.3 v can be because open circuit or shorted to ground. the inside of my connectors where bended wide because unplugging a hundred times. I simply bended the inside of the connector back with a flathead so it would make easier contact.
if you want to test this properly you can connect your compressor directly to your battery, just couple seconds to exclude that your compressor is fine. If this works either the pressure sensor faulty or open circuit,(in my case the connectors).
good luck
