My Air Con is playing up yet again. I have plugged into VagCom and get the fault :
00792 - A/C Pressure Switch (F129)
31-10 - Open or Short to Ground - Intermittent
When I drive the car with air con on, it will switch to ECON, I then press AUTO and it will switch the Air Con back on for a few mins then will go back onto ECON. It does this a couple of times then you can't take it of off ECON until you have erased the fault.
I ran a couple of tests on the pressure switch and the wiring using a jumper to see if the conpressor switches on (which it did). I thought it was the pressure switch that is faulty, so I brought another one. Guess what still didn't work. The only other reason is low on gas, so got it re-charged. Excellant it started working, well for a day. I have now got the same problem.
Has any body got any ideas on what I should do next???

Any advice would be much appreciated.
