    TT mk1 ac compressor dormant

    new to this so be kind
    2001 audi tt 180hp quatro 135k miles
    new ac compressor installed
    100 lbs static pressure on ac system
    Problem compressor clutch is not engaging
    both fans run constantly abd for 5 minutes after key off


    vcd codes
    01274 air flap positioning motor v71 41-10 - blocked or no voltage - intermittent

    00604 Potentiometer positioning motor for air flow flap g113 30-10 open or short to plus intermittent

    00797 sunlight photo sensor g107 30-00 open or short to plus

    All related fuses checked

    Replaced the following :
    Fan Module --- both fans -----compressor---condenser---expansion valve --- flushed system
    high low pressure sensor

    actions taken : unplugged compressor clutch hooked to 12 volt source started car, compressor engaged properly
    this test to prove compresor was not seized

    I accessed the onboard diagnostic on the climate control pannel :

    code 20 shows 13.6 volts ac clutch
    code 52 shows 0
    code 53 shows 111


    At this point I am about ready to seek a dealer OR find a high elevation that is near a low elevation

    Welcome.

    Since this is the VCDS forum and you have VCDS, we ask that you post an Auto-Scan for context.

    Hello Allem


    Fix all faults in 0x08 and check that the correct PSI switch part number is installed and functional, what about ECT cut out?

    Post a scan please........

    I assume you want a clean slate to work with and understand BUT this car is 17 years old..
    we need to be realistic on effort and value.
    My search is for the reason for the failure of the ac compressor clutch getting 12 volts to operate.
    Do you see any thing in that list that might cause this
    I know the sunlight photo sensor is not at fault as it has not been hooked up for years.
    The Other items I am not sure about .
    would not the ect set a code.

    Not always.....ECT or even ambient ECT could be reading below spec and turning off the AC.

    What do block values report in cluster and AC/heating?
    Dude if seeking diagnosis maybe do tests because your repair process so far is not realistic & it is you who has just changed a ton of stuff here.

    Did you trace the 12 volt lead to AC clutch with a meter and using the RTFB in WD?

    The ambient temp is showing correct on the center display of the pod .
    haven't learned block values yet will look into it.
    battery removed from car while compressor installed is that not the procedure to save settings.
    I admit that I can remember rolling cars over with a mule to work on them but all this computer stuff is simply
    youthful arrogance.
    I will continue your suggested items and report back.
    Including the 12 volt lead you mentioned as i was hoping the scanner would pick up something before I had to do that
    Yes I have a
    bentley is there a better one ?

    Stop acting old with the opposition to learning new shit.
    Erwin will help too....but RB for that old heap is fine.
    Let me see I don't have power at compressor so I will change the aforementioned and than cry it's about electronics and newer technology.

    You're your own worst FOD!

    Come on I'm now the old guy too someone kick this and his mule in the Ass please.
