Golf 6: Read Speed & Write MFA+ Data

Hello everyone,
I signed up on this forum to learn more about the CAN bus and to hack my Golf 6 .

Here's a brief introduction about me: I'm 24 years old and an engineer specializing in Mechatronics. My experience with CAN bus has been limited to controlling testing machines/equipment, which involved configuring and uploading software using tools like SEW or similar. Otherwise, I don't have extensive knowledge in this area.

I connected my Arduino Mega to the Comfort-CAN bus of my Golf (manufactured in 2010) using an MCP2515 and a TJA1050, and I was able to successfully read various messages.

Right now, my priority is to extract the current speed from the news reports and then, in the next step, write something about it for the MFA (presumably a specific organization or platform).
Unfortunately, I was unsuccessful in my search for the correct CAN IDs or possibly a guide, and now I hope that you can help me directly .

Here's a brief list of the IDs I read:

0x151
0x291
0x2C1
0x2C3
0x351
0x359
0x35B
0x3C3
0x3E1
0x3E3
0x42B
0x470
0x497
0x523
0x527
0x531
0x54B
0x555
0x557
0x571
0x575
0x58C
0x5B5
0x5E1
0x60E
0x621
0x62F
0x635
0x651
0x653
0x655
0x658
0x65D
0x65F
0x661
0x66C
0x67C
0x6CA
0x6DA
0x6DB


Thank you very much and best regards.

Sure, here is the translation of the text from German to English:

"Hi,"

With a little searching here, the ID should be found along with its speed.

It would be easier to use the "Message Changes" view in KCANMonitor to observe a cycle, preferably with the engine off. This allows you to quickly see where and how different values are changing.

Color explanation: - dark green: increasing bytes - light green: decreasing bytes - orange: toggled bytes - blue: spontaneous changing bytes

Best regards, Rainer.

I'm bringing this up again. Is there possibly already an ID for the speed, so that I can send it to the AI? So far, I haven't found it here .

Has the CAN ID 0x351 already been tested for speed?

Best regards, Rainer.

I need to check this on the car first, I thought it might have already been figured out, so that I can basically send the km/h to the instrument cluster (KI) from my computer .

Otherwise, I still have to wait for my connectors, then I can directly connect it to the car and read the data.
Although I currently have a Passat B7, it's the same platform .
