    No response from controller with HEX-NET

    Hello!
    I recently bought a HEX-NET wifi, and it have worked perfectly on my car (Audi B7 and VW Tiguan) with both wifi (pc) and cable (pc)
    VCDS mobile also worked correctly.
    Earlier this week I tried to access the controllers, but got "No response from controller" on several controllers, including Engine, auto hvac and a couple more (dont recall) Autoscan is the same.

    Instruments and centr electric seems to work fine, I can access those and read fault codes.
    The engine runs well, the climate controller the same.

    Last night i tried my buddys hex-can usb cable, and suddently i could access the whole car. It was with mine laptop, the only differene was the cable.
    The B7 is canbus but communicates via k-line if im no mistaking.. Is there an issue with the hex-net or my computer?


    Test for hex-can usb:



    Test for the hex-net (tested with USB)


    (I can see that CAN is saying testing, but according to ross tech website thats okay)

    Any thoughts?

    The Audi B7 has some modules on CAN, and some modules on K-Line. Depending on how it is equipped, it may even have some modules on a second K-Line.

    Auto-Scans would be a good start.

    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.

    It does. It shows us exactly what is and isn't communicating.

    You definitely missing 01-Engine.
    What engine type is in this car?
    Does this car have a manual or automatic trans?
    You're likely missing a number of other modules, but I'm puzzled as to why.
    It's not that it's missing everything on CAN. Your ABS talks, and it's on CAN.
    Can you post the scan you made with your friend's HEX+CAN please?

    Can you try to make an Autoscan again with a charger connected or car running @ idle and post ?

    OK, so what we have here is a Franken-car.

    BTW, I made an error a couple of posts up, the ABS is not what I found on CAN, the the airbag module is; but in the end, we can rul out that the problem is no communications on CAN. Most B7 ECUs are also do diagnostics on CAN, not on K-Line, which is why I was wondering about that.

    TBH, I'm a bit stumped as to what's going on here. But since it's now clear that all the modules you're having difficulties with are on K-line, we know what to focus on. It would be interesting to put an oscilloscope on the K-Line at the diagnostic connector to see if there's a noticeable difference between the HEX+CAN and the HEX-NET on this car. However, I'm guessing you don't have an oscilloscope?
