VW Golf IV: Can Bus Hacking?

Hello everyone,

I'm quite new to the CAN field, so please don't laugh at me right away .
I want to read the interior CAN and the engine CAN bus data from my Golf IV, but I haven't figured out yet where I can tap into the signals. Do I need any special adapters for that?
I bought a test microcontroller board that I wanted to use to monitor the CAN bus, so there shouldn't be any hardware issues.

Thank you in advance!

Sincerely,
Sinister

As far as I know, you only get CAN functionality in the radio if you have at least one Delta-type radio. Unfortunately, my Bora only had a Beta-type radio.
Where can I tap into the CAN bus? Should I connect directly to the comfort control module? Does anyone have the pinout diagram for that connector?

Please provide me with the part numbers for the KSG (either 1C or 1J) or simply use the two organ cables.

I just checked, and it's the same for both KSGs:
6- OR/BR - CAN-LOW
9- OR/GN - CAN-HIGH

At 1c, it's 100 kbit.
At 1 GHz, it's 62.5 kbit.


Best regards.

You're welcome.

I just realized that I don't have any USB extension cables anymore. Theoretically, the Comfort-CAN should also be accessible at the climate control unit, right?
