OK - so this ain't your typical vehicle!

Back-story:
I just updated VCDS SW to the latest release version on my Surface Pro 7 together with an update of the dongle firmware on my trusty HEX-NET. I then connected to my MQB platform test-bench (in Access-Point mode)

My test-bench is a mongrel mix of modules ("Heinz" version to use an Aussie vernacular) - meaning that the modules have been sourced from wherever I could find the cheapest unit at the time of building. Needles-to-say, the set-up is insanely DTC rich because only key modules are connected and lots of sensors are missing - but that's OK. Here's the auto-scan using the SW version just installed:

What's happened:
When I tried to access the CAN Gateway module directly, I got the message in the first screen below:
bR7p3NA.png


When I select "Yes" in the dialogue-box on the first screenshot - VCDS loads the correct EV_GatewLear 006010 from the ASAM dataset as shown for the hex19 module in the auto-scan above
When I select "No" on the first screenshot, the remaining 2 x screenshots eventuate

If I use my HEX-NET2 which I also updated (again in AP mode) - none of the above happens; the dongle works perfectly on my test-bench

Now, as I have said - the modules on my test bench came from various places and when I read the VIN on the hex19 module, it is different to the VIN on the auto-scan (which comes from the VIN that is in the hex17 module), and CP errors abound. And in truth, the little white-lie in the first screenshot really doesn't matter because its only a test-bench and both dongles work perfectly well on the real car that currently sits in my workshop.

BUT, purley from an intellectual perspective- is the dynamic above explainable? Why does it happen on HEX-NET and not on HEX-NET2?

In the meantime, maybe you can explain more clearly what you did.
What was the exact sequence of things? Autoscan first or 19 first? Did you swap for the HN2 without restarting VCDS? Once you had the HN2 connected, what did you do? An autoscan? Go directly to 19? Et cetera :)

Does the HN2 talk DoIP when it does this or UDS CAN? An Autoscan with the HN2 would probably be helpful.

  1. Autoscan first or 19 first?
    From memory-No. Because I have so many DTCs on the test-bench, there usually is no useful information for me in the auto-scan report. However, as is my normal practice - I did "Test" the dongle connection from the "Program options" screen as my first step. So, I went directly to the "Select Control Module" screen and selected the hex19 module from there. It was only after getting the odd message that is in my first screenshot that I ran the auto-scan report - I really wanted to see how HN1 reported the hex19 module. And to be clear - I did start an entirely new VCDS session after updating the 2 x HEX-NET dongles.
  2. Did you swap for the HN2 without restarting VCDS?
    I can't be certain, but I don't think that I closed the VCDS session before starting again with HN2 connected. However, I can remember re-testing the HN2 connection in the "Program options" screen again before proceeding.
  3. Once you had the HN2 connected, what did you do? An autoscan? Go directly to 19? Et cetera :)
    I didn't create an auto-scan with HN2 connected - just confirmed the different dynamic, then closed the VCDS session

Shaun: Hi - I didn't intervene with either dongle to force either DoIP, or UDS CAN. So I guess that whatever default protocol that VCDS uses to speak is the language that was used in my session (of course, my humble test-bench doesn't have anything as fancy as DoIP)

Here is an auto-scan made with HN2- as requested:

@Eric / @Shaun : Update!

Galvanized into action by @Eric interest about the sequence of steps (which I thought to be an infinitely insightful question) - I tested his hypothesis and bingo, it does seem to matter!!

With further testing, the dynamic is now repeatable and it's the same with both HN1 & HN2 - and it seems to apply to ALL 5 x modules on my test-bench (even the hex17 module which has the same VIN as recognised in the auto-scan).

It appears that if I start a VCDS session without first making an auto-scan, the VIN error message appears when attempting direct control/access to a module. However, if I precede access to any of the modules with an auto-scan - normal operation happens!!

I have no idea why -but as I said, it's just a test-bench !!

It's almost as if that VIN dialog was trying to tell you something, isn't it? ;)

Simple. The HEX-NET or HEX-v2 is supposed to retrieve the VIN over OBD2 at power-up, and VCDS will then rely on that. Not having an engine on your test stand, you are defeating that process (no, we can't make an autoscan at power-up to scour for a VIN in people's test stands, that would take too long). When you do your autoscan, and VCDS sees the HEX-NET/v2 is unable to provide a VIN, it will try whatever it can to get a VIN from the modules as it's scanning them. (New in 21.9 is that we will no longer be making assumptions based on part numbers if the VIN is missing, and will inform the user with the aforementionned dialog on individual module connection instead). If VCDS succeeds in its own VIN retrieval, it will then "inform" the interface of the VIN it found, and that should stay persistent until the next car-side power event. The newly found VIN should also stay persistent in VCDS under some conditions (if it recognizes it's the same car), which is why I asked if you had restarted VCDS before making that 'porkies' statement :)

@Eric : Thanks again for the insight - I wasn't aware that the VIN discovery process was altered in SW ver 21.9 (your response also explains the sudden existence of dialogue box containing the VIN message - which I hadn't recalled seeing before).

In retrospect and having understood your explanation, I'm now of the belief that my totally scurrilous "porkies" accusation was greatly exaggerated!! I shall repent and do penance for my sin (only kidding - I no longer have Catholic guilt and I no longer believe that the Pope is inflammable!) :D
