yes its in the video where you would expect it to be but its defiantly not there tried to follow the pipe as far as I can the only place I think it can be is on the bulk head behind the egr valve area.

[betrescudan]

can be only on circuit of compressor...follows the aluminum tubes to compressor

Thanks m8 going to strip of engine tomorrow and see where it is its somewhere but well hidden I know on the golf gti its at the front just next to the compressor. I will find it tomorrow .

thanks for your help much appreciated.

Found where it goes thanks to mrriadh the person who sent me the diagram hidden in beside the radiator. number 18.

tried to upload so you could see it wont do it for some reason

Great found it now to test it but how don't have any meter to test resistance someone told me to put a paper clip into two of the plug connections and it should start working if the pressure switch is at fault.
But I don't think it wise to do that as the air con has it own ECU would work out quite expensive if I shorted it out.

found this which might help http://www.youtube.com/watch?v=tMi3VDkPdCo

This is the error codes I am getting doing a vag k+can commander I have translated from German. finally got it to work

OK system description climatic PQ35-090
1/2 00E5 status permanent error
lower limit exceeded.

2/2 0333 high pressure generator
G65 status sporadic error
cut in short to ground,

G65 is the pressure switch I have found that out at least

Looks like betrescudan was correct should have had more faith. thanks

The switch was faulty and all DTC codes cleared but still no cold air god I was cooked today all re-gassed found out clutch is always engaged on the golf mk5 any suggestion's appreciated don't really want to go for the control valve on the compressor yet need to try easier options first getting expensive now.
been driving around all day cooking but no new errors.

There is no clutch on these compressors, They turn all the time.

I often see the plate on the end of these compressors with sheared splines so the shaft inside does not turn. You can see this by the bolt on the end not turning.

Type "SSP 208" into google and this may help you understand the system.

Ffs smokey beet me to it, was stalking.

there is something about engine stopped , belt off? , turn by hand should be 'lumpy' if not the doodle has snapped

[WOODWARD395]

Ok went back to basics and started at the compressor checked power feed getting feed and ground everything I need for the pump is there the valve is fluctuating you can see it on the gauges but no pressure increase the compressor is not compressing. it could be the valve so what do I do change the valve or the whole compressor. cost of valve approx. ?80 or compressor ?274 if I change the valve and then need to change compressor ?80 down the drain.
if any one knows how to test the compressor without a strip down I would appreciate it.

checked it out today only wish it was but that still would mean a new compressor at nearly ?300

on g5 there is control vale (as you finaly discover) so compresor work all the time but valve control displacement of compresor like we can say eficency from 10-90%...in you diagnostic toll you can see how much curent this valve surge..about 850mA is max..so IF you see that vale surge 850mA and there is still only small diference between IN/OUT presure..then its time to remove compresor..cleane inner parts vhere is conections for pipes,remove valve plate..clean it from any debris,pun new valve and maybe all finaly work as it shoul be

Confused

photos or it didn't happen
