DQ250 DSG: CAN Bus Connection & Troubleshooting

Hello, I'm new to this forum.
I want to install a DSG transmission (DQ250) from a Golf V into a vehicle without a CAN bus system (Golf MK III 2.0L 16V).
From a hardware perspective, almost everything is complete; only the drive shafts need to be manufactured and the wiring needs to be installed.
Let's get to the point. To develop a control unit that can inject arbitrary signals onto the CAN bus, i.e., a CAN I/O box, I don't need to worry about it because I already have someone who can handle that for me.
'I need someone who does this professionally. I just need the relevant addresses and messages that come from the ABS/ESP and engine control units.'
I am willing to sit down and monitor the CAN bus myself in order to create a list of important addresses and messages from it.
Unfortunately, I am missing a suitable vehicle, specifically a Volkswagen Golf MK 5 with a 2.0-liter gasoline turbo engine (engine code: AXX) and transmission code: HBQ.
I'm looking for this combination because the transmission is specifically from that configuration, and I want to be absolutely sure that the messages are compatible.
Originally, the plan was to complete this project by mid- or late-2011.
If anyone has information that could be helpful to me, I would be very grateful if they could share it with me.
I would gladly pay for this information or find another way to show my appreciation, as I understand how much effort it takes to create such a list.

Do you only install the gearbox, or also the engine and other components?

Originally, the plan was just to install the transmission, as it mechanically fits the 2.0L 16V cylinder head without any further modifications.
If my original plan proves completely unfeasible, I would resort to using a modern 2.0L turbocharged gasoline engine with an ECU that supports CAN communication.
However, during my research, I came across a page http://www.dsg-corrado.de/ where a DQ 250 transmission is being used in a Corrado with a G60 engine and a custom-built control unit.
So, I assume there must be a way.

Hello Dennis and everyone else,

I would like to know if the problem has been resolved.
A friend has asked me for help adapting a DSG transmission to a Lupo 3L, as his knowledge of CAN-bus systems is rather basic. I'm more familiar with it, but unfortunately, my experience with VWs only goes back to cars built in 1990.

The Lupo already has CAN communication (hopefully with all the relevant information), and a suitable gateway is available – in principle, I think it should work. However, I'm not yet clear on which messages the DSG expects, when, and how.
Can you or anyone else here help with this?

Thank you and best regards,
Maren.

Hello Maren,

Unfortunately, the problem with the DQ 250 has not yet been resolved.
I'm still missing the CAN bus matrix for the residual bus simulation.
It's not worth starting a project like that without the right tools and resources.
Regarding the DSG transmission in the Lupo, is it a 6-speed or a 7-speed gearbox?
I suspect you'll have to implement the residual bus simulation using a microcontroller anyway, so you might as well generate missing messages while you're at it.

Hello Dennis,

Is the system working properly now? We would also like to use it in our renovations.
Unfortunately, I haven't been able to reach anyone under the name "DSG Corrado" recently either.

Regards,

Daniel.

Hello,
Okay, here's the translation:

"First of all, I'm sorry... I can understand German, but I can't write it."

"How's that project going? Right now, I'm also working on a DSG controller. I've reached the point where I need to actually test the software and verify that all my CAN messages are correct. I'm even planning to sell it if it works out. My test car is an old VW with a 250hp turbocharged engine. Just curious if you managed to get it working and what the results were."
