    2008 Jetta A/C Diag. question

    A/c not working.

    Trying to make sense of how to know if the control valve or the compressor is at fault

    The shut off code =6
    Compressor current (actual) = blank
    Compressor current (specified) = 0.820 A
    Comp. load 4.8Nm.
    Refrig. pres. = 10.0 bar

    I checked the resistance = 11 ohms

    Hmm, Shut Off code = 06 - appears to be "The compressor has been switched off by the 'Econ' function."

    Do you want to try hitting the 'Auto' button, or the 'A/C' button, or whatever you have? Report back please.

    The Code 6 is what I get when I turn the system off.........this is normal.

    The line I'm confused on is; Compressor current (actual) = blank

    The line that give me hope is: Comp. load 4.8Nm with A/C on.

    BTW there is no change in the A/C gauges from A/C on to Off

    Okay, I know, if you would do some more testing for us please. Does it go to '0' and stay at '0' for all of the time the A/C runs?
    Does MVB 002.1 appear when A/C on?
    Does MVB 003.1 change at all when A/C is on?
    Using either intrusive current measurement or a hall-effect current clamp; does the current through the compressor control valve look anywhere near the Specified value?

    The valve in the compressor is kaput.......very common costs peanuts!

    As always things screw better when wet and slippery right?

    - Compressor failures are a common issue in many of these vehicles., almost as common as the failing N280 valve ... you should have a close look at the refrigerant oil, if it is NOT clear or clean, you should replace the filter dryer and flush the system.

    This Ross-Tech forum post linked below, maybe helpful in the future

    Hope this helps, stay cool!
