Audi A4 B7: Needle Sweep Explained

Hi everyone, sorry my post is in English because I don't speak any German.
I'm seeking help trying to achieve needle sweep functionality using an Arduino and a CAN bus shield on an Audi A4 B7 dashboard. I'm encountering a few problems, firstly, which CAN port on the dashboard should I connect to? There are four different CAN ports available.
Convenience CAN High.
Convenience CAN Low.
Infotainment CAN Low.
Infotainment CAN High.
CAN drive low.
CAN drive High.
CAN diagnosis: Low.
CAN diagnosis: High.
Is it possible to connect via the OBD2 diagnostic port?
Sure, here's the translation:

"What are the CAN addresses for speed and RPM?"
Sure, here is the translation of the text from German to English:

"I am writing to you today to request your assistance in a matter that is very important to me. I have been experiencing some difficulties with my health recently, and I believe that it may be related to my work environment. I would like to discuss this issue with you further, and I hope that you will be able to provide me with some guidance."

I hope this helps!

Hi,

You can communicate with the dashboard using any of the specified CAN channels. However, the "sweep" function should be a setting that is configured within the dashboard itself.
You can use software like VCDS to configure it accordingly.

Best regards,
Rainer

Thank you for the reply. The sweep function cannot be performed using VCDs on the Audi A4 B7. However, I have been able to communicate with the instrument cluster and perform the needle sweep via the CAN bus.

"So, you're saying the dashboard doesn't support the sweep configuration option, and you were essentially sending out false RPM readings?"

Okay, here's the translation:

"Exactly. RPM and speed. Still in the process of tuning because the engine RPM is increasing faster than what the speedometer indicates."

Okay, here's the translation:

"Nice!"
