CAN in VDO COMBINATION INSTRUMENT

HELLO everyone! Here's the situation: Someone seriously borrowed a CAN module from a company (likely for research purposes). This module was intended for experiments on a VDO AUDI A3 2003 dashboard. It was soldered to a CAN sniffer and a microcontroller (LPC2129), along with a VAG-RUS software program and the appropriate adapter. The problem is that the dashboard was programmed to respond to commands from the external microcontroller, sending out a specific VAG code. The report shows the data exchange between VAG-RUS and the dashboard. Here's a snippet from a log:

The problem lies in sending this command from the microcontroller.

The board responds immediately.
300 1 A8

Does anyone know how to establish a connection? Thank you in advance for any information you can provide.

I'm sorry, I don't have the energy to write in English right now, so please translate this text for me into English.

First, a question: What is VAG RUS?
You're trying to open a TP 2.0 channel for diagnostics, if I understand correctly?

I suspect you're having network management issues. Please post all IDs between 400 and 430.

Unfortunately, I haven't done much with TP 2.0 yet, but I could send you one from TP 1.6 if you want. There isn't a huge difference, just minor details. <!-- m -->:-)http://www.duckduckgo.com/language_tools?hl=de{MARKER}{MARKER}

Please excuse me! VAG-RUS is VAG-COM version 607-3UD.
2. tp 2.0? But, according to my understanding, VAG-COM works normally with this channel.

It is difficult to translate (or transfer) to the Russian language. I suspect you are offering me the information. I agree. In the near future, I will gather a lot of information, and I will definitely share it with you.

I will notice what connects to the gateway first using VAG-COM.

However, it cannot be seen because the KOMBIINSRUMENT is placed on the table.

Unfortunately, I can't fully inspect the AUDI car because in Novosibirsk, there are mostly Japanese cars, and very few AUDIs.

While working with VAG-COM, the following was discovered:
At the departure of the unit.

200 7 07 с0 00 10 00 030 01

The multi-tool responded.

207 7 00 D0 00 03 51 07 01.

If I had the command...
*200 7 07 с0 00 10 00 030 01* with a microcontroller, that is the response the panel sends.

207 7 00 D0 00 03 51 07 01
207 7 00 D0 00 03 51 07 01

207 7 00 D0 00 03 51 07 01
207 7 00 D0 00 03 51 07 01.

I believe my mistake was not confirming the receipt of this message.
