Audi A4 8E Door Control Unit 8E0959801A, Desk Stand

Dear CAN hackers,

I stumbled upon this while working on a home automation project, where I wanted to use the TSG, or rather, the motor attached to it, to move a projector ceiling lift.

I'm using a Raspberry Pi for control, and I can already communicate with the TSG using an MCP2515 CAN board. It responds politely with

Code:

404 [6] 04 04 00 00 00 00 404 [6] 04 14 00 00 00 00

to register to participate in a boxing match, as well as with...

Code:

4B9 [5] 06 00 00 04 00

to indicate that it feels locked via the key fob (06) and that it thinks it's open by 04 rotations, at least according to the information I could find online or here about the power windows.

If I connect the pin for the door contact switch to ground, then pin 06 will become pin 07.

If I send a command 291, a relay clicks cheerfully, simulating the operation of a non-existent motor for opening/closing the lock cylinder. However, the motor cannot be "persuaded" to turn with command 181, even if I send a command 271 03 every 100ms.

Do you have any suggestions for me? Am I missing something? Is a cyclical ID required to indicate that the parental control feature is not enabled, or is the "181" code incorrect for the Audi 8E?

Unfortunately, I don't have an Audi 8E available, so I can't log any trace data myself. I'm therefore hoping for a little help from you.

Best regards from the Ruhr area... and thank you in advance!
