Hi, thought I'd go down a different route with my question. VCDS says my high pressure duty cycle is at 24. 5%. Does this seem right? Thanks

Hi, I ordered a new ac pressure switch online and the one that arrived is different as in it has a longer nut section. i have spent hours trying to find the same one as the one on my car but everytime i search the part number on mine only the other one comes up. There is a couple of secondhand ones on ebay but i want new. i dont understand why i cant find one When i watched vids on how to change it the ones in the vids look like the one i have. mines like the top pic Does anyone know where online in the UK i can get one please Thanks for any help

OOOppps posted twice Hello everyone, after owning i rekon over 100 cars i now have my first Audi and i love it, 2006 A4 B7 2.5TDi Avant

So my aircon hasnt worked since i bought the car last year, stuck it into a garage and was told the compressor was knackered. Before i fork out over £600 i thought i would investigate first. ACCORDING TO VCDS I ONLY HAD 2 BAR OF PRESSURE SO HAD IT TOPPED UP IN A GARAGE AND NOW SAYS 6 BAR Using VCDS I fired up the car and turned on the climate control on auto and set temp to low. ECON IS OFF VCDS says.... AC VALVE CURRENT (N280) 0.652A AC VALVE (N280) DUTY CYCLE 60.1% HIGH PRESSURE SIGNAL (G65) 24.5% REFRIGERANT PRESSURE 6 BAR COMPRESSOR SHUT OFF IS 0 LAST SHUT OFF 1 SECOND TO LAST 12 THIRD TO LAST 1 RADIATOR FAN REQUESTED 14.8% RADIATOR FAN ACTUAL 30% AIR QUALITY SENSOR NOT INSTALLED FRESH/RECIRCULATED AIR REQUEST 40 RADIATOR FAN STARTS UP With a multimeter i tested the feed to the compressor valve and was getting 9.5v When I turn the ECON on the AC VALVE CURRENT AND THE AC VALVE DUTY CYCLE GOES TO 0 THE CURRENT SHUT OFF CRITERIA CHANGES TO 6 THE RADIATOR FAN REQUESTED AND ACTUAL GOES TO 0 THE REST STAY THE SAME THE FAN STOPS VOLTAGE DROPS TO ZERO ON THE FEED TO THE COMPRESSOR VALVE I have a new pressure sensor coming as see that can cause alot of problems, am i right in seeing that this can be changed without draining the system? Ive watched loads of utube vids and read alot of posts but now a little stuck Do all these look about right? I thought the ECON was an a/c override but find it strange that things turn off, is this correct? I would appreciate any help or advice on any obvious problems with these readings or other things to try to diagnose where the fault is. Many thanks M9GUK
