    Audi A4 Quattro 3.0 B6 AC questions

    Hi
    I need to confirm and see if my AC pressure switch also known as low/high pressure switch is working, and also if my AC clutch is engaging.
    Is it possible with VCDS to monitor this sensor and see it working as well as the AC?
    Thank you

    Hello,

    Is it possible with VCDS to monitor this sensor and see it working as well as the AC?
    Depends, do you have the [08-Auto HVAC] controller? and if so do you have a value in Measuring Value Block group(MVB) [001], field 2.

    If so you can see the "High-Pressure Signal (G65)" and there is no Low Pressure sensor on this vehicle.


    Please include an Auto-Scan if you have any more questions, hope this helps,

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.
