    Oh right, so this is like my old car. What does [Options] -> [Self Test] show for CAN status, with engine running? If it shows "Testing" you might have a problem with the wiring to the DLC, like Uwe said, because there should definitely be CAN traffic on the port.

    OK, Shaun, I'll go out and run a complete autoscan, and I will try the Options -> Self Test for K1 and K2. BTW, this car does not have any aftermarket equipment installed anywhere. I'll be back soon.

    Yep, which is why I'm pretty confident it should work, despite being quite odd in terms of how it works.

    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.

    Shaun, here is the entire scan. Addresses 01 through 07 did not read. The self test read:

    Dear Uwe, please see the scan data I sent to Shaun. BTW the CAN reads as not ready, but Audi seems to be able to read the 01 through 07 addresses, and on some occasions I can read those addresses. As I mentioned earlier in the thread, the 01 was seen momentarily on the first scan, but no data was saved or appeared on the scan output.

    The 01-Engine, 02-Auto Trans and the 03-ABS have all been read at one time or another.

    The following is from a time that I was able to read addresses 01, 02, and 03:

    In the scan two posts up, everything that talks in on K-Line, and everything that doesn't is on CAN.

    "CAN Not Ready" could be a lack of connection to the car's CAN bus, possibly dodgy pins in the car's DLC, or a wiring problem in the car, or it could be some sort of internal failure in the HEX-NET.

    I think the only way to sort this out is process of elimination. What other cars do you have available that you can plug the HEX-NET into?

    Dear Uwe,

    Well, I got side tracked and didn't get a chance to try the HEX-NET on the other Audi, a 2015 A4 Quattro Prestige until two days ago. The HEX-NET did read the CAN bus. It did take a bit of time for the CAN bus to be ready, but all of the addresses were read.

    Can you suggest a protocol for trouble shooting the inability the HEX-NET to read the CAN bus on my 2008 A4?

    I tried the HEX-NET on the other Audi, a 2015 A4 Quattro Prestige, and the HEX-NET did read the CAN bus. If I'm trouble shooting the cars OBD-II bus at pins 6 and 14, how would I be able to do that and what readiness should I expect to get?

    Would you have a photo of the OBD-II connector showing which pins 6 & 14 are?

    Thank you,
    Binsu
