HEX CAN Interface Test -> kein CAN? | Posts 32+

Okay, then tell me where you found mold on the Touareg, Phaeton, or A4 (8EC/8ED/B7). Then I'll go out and check it myself, and we can talk about it later.

Classic locations are the CD changer and the navigation control unit.
Of course, the radio as well. The MOST cables are the rigid, orange fiber optic cables.

Best regards, Jochen.

Don't take this the wrong way, but you're talking nonsense. Anyone who wants to can try finding the MOST cables in an RNS-E, but I certainly can't find any – and strangely enough, neither can anyone else who has supposedly worked on one before. (See the attachment; I took apart an A4 center console...)

'What does 'einig' mean?' ... 'The FACT is that the MOTOR-CAN and ComfortCAN are active in the LEON, and the control units communicate with them. Diagnosis is performed via the K-LINE. That's it.'

I apologize, I made a mistake with the B6.

I mistook it for a Volvo V50; it does this using the MOST protocol.
The Phaeton also uses MOST; it communicates with the display via MOST, but additionally has an infotainment CAN bus, which is correct.

With so many vehicles, it's easy to lose track of them.

Best regards, Jochen.

In the Phaeton, you only have MOST technology between the navigation CD and the display/control unit; it's not even remotely comparable to, let alone identical with, the Audi A8. In the Touareg, there is no MOST technology at all.

Apart from that, we are getting off topic.

@legolas09

I'm sorry, but I have to agree with Jochen_145.

We once had a colleague install an ASV engine control unit (ECU) from a SEAT Leon into an Audi A3 to demonstrate chip tuning.
The engine was running, the control unit was working correctly, but the instrument cluster was completely dead!
Must also have no CAN communication: Error in the corporate bus.

So, now the CAN connection to the AI was missing, all because of swapping out the control unit!
Therefore, your statement is not entirely correct!

Perhaps Jochen_145 knows more about ASV, at least it seems he actually owns one, unlike you.

I'm sorry to say this, but I can't let that stand.

God bless you.

I don't think we need to make a general "xyz is right and abc is wrong" thing out of this. The fact is that the Leon also has CAN, and no one who really looks at all the systems would deny that. Similarly, it's true that the Leon is based on the Golf 4, not similar to the Golf 3 as some claim. No one denies that a CAN drive isn't used with the ASV engine, but this is obviously different for other engine types. However, what needs to be said is that the arguments presented by Jochen weren't convincing in their current form. Whether it was due to recklessness or lack of knowledge doesn't matter at this point, but if I'm going to argue a point, I should know what I'm talking about, or I shouldn't say anything at all. Everyone makes mistakes sometimes, and I'm not exempt from that, but making baseless claims isn't the way to present yourself as competent or gain friends.

Okay, even with an AHF (which should be almost identical)...the CAN chipset is present and active. The AHF was installed in the LEON before the ASV. Why would they cut corners in that case?

Okay, let's agree that some vehicles apparently don't have a CAN bus in the control unit. The question then is how the instrument cluster receives its signals, and how systems like airbags and ABS communicate with each other.

No one denies that a CAN drive is not used in conjunction with the ASV, but it is obviously different with other types of engines.


I'm sorry, but if you look at the entire thread again, it's exactly what we're discussing here, and what legolas09 ultimately denied.
I haven't claimed anything else.



However, what needs to be said is that the arguments presented by Jochen were not consistent. Whether it's due to misinformation or a lack of knowledge, it's irrelevant here. If I'm going to argue a point, I should know what I'm talking about, or I shouldn't say anything at all.


This is simply incorrect information, as I have already stated, and it's not based on any real knowledge. I am perfectly aware of where I can find the detailed route maps for all VAG vehicles.


Everyone makes mistakes, and I'm no exception. However, making baseless claims is not a way to present yourself as competent or to gain friends.

If you present it this way, I'd be happy to pass the ball back to you.
Since you run the OBD section, you should be familiar with the CAN bus, as you are positioned here as an expert (and rightfully so!).

The CAN bus can more accurately be described as a 'passive' communication system, meaning it's not a 'question and answer' type of interaction.

You are mistaken here. The diagnosis runs on a separate CAN diagnostic bus (except for Audi A4 (8E)). This bus is chronically inactive until the diagnostic device initiates communication. Then, and only then, data can be found on this bus, but even this data is only available upon explicit request, not as a general 'broadcast.'


You've demonstrated a lack of complete knowledge here. The fundamentals of CAN communication should be well-known. And CCP or XCP are commonly used in vehicles today.

@ legolas09:

My Leon receives information about speed, engine RPM, etc., in a 'classic' way via analog cables. These cables even extend to the Raido (presumably a specific component or system). -> That's why I compare my Leon more to a Golf 3 than a Golf 4.'

All things considered, I would say that in the heat of the moment, a few people who thought they were knowledgeable about their area reached the limits of their understanding. As you can see, there's always someone who knows even more.

Everyone got their fair share.

Okay, let's close this thread now and continue the discussion constructively and peacefully.
Considering that a valuable exchange of information has ultimately taken place here, I think:
Next time, I'd like to order again.

In this sense .

I think that's enough now, right? It has nothing to do with the HEX-USB+CAN anymore. Jochen, please accept that other people can also be right sometimes. Your behavior is childish.
