She's not cold fellas.

SmokeandMirrorsTrick on Mon August 08, 2011 10:06 AM User is offlineView users profile

Year: 2002
Make: VW
Model: Cabrio
Engine Size: 2.0
Refrigerant Type: R134.
Ambient Temp: 85
Pressure Low: 55psi
Pressure High: 125psi
Country of Origin: Germany

Compressor is running. Recovered 134 and added proper charge by weight. My only reference right now a an r12 book from 1972 and according to it the compressor is bad. Says something like bad valves inside. Any clue guys? Any help is much appreciated.

These compressors are known to have control valve issues. High side is very low if you have a full charge.

Great minds think alike... as soon as I saw high suction pressure and VW, first thing that comes to mind is the problemsome control valve on these vehicles.

Surprisingly, control valve issues are pretty rare on the GM V5 and V7 compressors. Too bad the rest GM doesn't build the rest of their cars like these compressors.

Control valve can be replaced, but it's not an easy job. Probably better off just replacing the compressor.

I replaced the compressor, R/D and the TXV. Flushed everything out, pulled a vacuum for an hour and a half. Properly charged the system and I was getting a vent temp of 35 degrees with the blower wide open recirc on while driving down the road at 40mph. While driving 40mph with the blower on the low setting and recirc on I got a vent temp of 28 degrees.
