    Auto-Scan, learn it, love it, live it... then check the fuses.

    Hello,

    Any ideas what could be wrong?
    Yes, The fault code in the Auto-HVAC controller says it all! There is a concern with the G65-Refrigerant Pressure Sensor, it's wiring or connections or perhaps the J255-HVAC Controller.

    B10AE/9481748 - High Pressure Sensor: Open or Short to Ground

    This forum post should be helpful.... Tis’ the HVAC Season

    Oh, one quick test is to disconnect the connector form the G65, see if there is any refrigerant/oil leaking from the system, indicating the G65 has a problem!

    If needed, links can be found for the Official Factory Repair Information.


    Hope that helps,

    drpeter


    ps... posting a complete Auto-Scan is best and can be helpful in many different ways..

    If this is anything like the golf mk5 the sensors leak and at the front straight down on the left by the radiators. My sister had the same issue on her mk5 golf.

    Thanks for the Auto-Scan...

    After you fix the "High Pressure Sensor" fault clear all the DTCs and hopefully the " no signal/communication" faults will clear too.

    And. . . do let us all know what you find. Success stories are great and help others here searching for answers to these types of concerns,

    The G65 is the High Pressure Sensor. It has 3 wires:

    • /1 = br, ground
    • /2 = li/ge, to HVAC (J255) T20c/2
    • /3 = bl/sw from fuse SC13 (5A)

    Unplug the sensor, make sure the electrical contacts are clean and dry... do you have ground and power on /1 and /3? Is the /2 data wire damaged or broken?

    Auto-Scan, learn it, love it, live it... then check the fuses.
