    Cannot Auto Scan with HEX-NET, USB, and VCDS 19.6.0

    Just auto updated the VCDS software on my laptop. I am using a HEX-NET enthusiast version. On VCDS, I tested the USB port via the laptop and the HEX-NET is found. However, when I try to auto scan, I get an error message:

    Scan: Auto-Detect
    Function not supported by the gateway
    VIN: xxx
    End------(Elapsed Time: 00:07, VBatt start/end: 12.9V/12.9V)-----

    Used to be able to auto scan, etc., with my setup before (2 months ago) with no problem.

    Can someone help?

    Just tried connecting with WiFi and using my smartphone/app. With auto-scan on the app, I get a different message: Can't check ASAM data in AP mode. Unable to reach server.

    Any thoughts?

    No, it wasn't. Tried with ignition on as well as engine on too.

    What are the exact results when you do [Options] -> [Test] in VCDS with the HEX-NET connected to your PC via USB and plugged into the car?

    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.

    Try again with the hood open - some newer models require the hood to be open for the diagnostics to connect...

    Should not affect the ability to do an Auto-Scan. The "Diagnostic Firewall" does not prevent reading data from modules, only writing to them.

    Can't check ASAM data in AP mode.
    This is expected, you don't have access to the outside internet in AP mode, and it needs to download data from the server. You can either use a wifi tether, or you can take it back inside and now download the data with VCIConfig -> "Check for Updates"
