I am not meaning to hijack anyone's work, just trying to bring the posts together so others can benefit from the lessons learned.
I figure it would be worth getting the information into one thread, and maybe @Cuzoe or @Chillout , it would be awesome if you can help to put the information here? Personally I am super interested in doing this to my 2018 R, and I think I have the hardware to do it. I was jumping through threads and I was hoping to put it all in one thread.
What do you need?
You can flash them all with ODIS or VCP. VCDS and OBD11 cannot be used to do this.
Please note, there may be newer copies of the software, and I will likely not keep it up to date:
You can find ODIS here: https://www.obdinnovations.com/odis-diagnostic-software-v4-3-3-digital-download/
You can find VCP here: https://vcpsystem.com/k17,vcpsystem-reg.html
Verify the hardware versions required
- 5Q0907376A - hardware version you likely have
- 5Q0907376B - firmware version you likely have
- 5Q0907376C - Arteon firmware version you want to get to
Where is it physically located? see the first post here for the diagram: https://www.golfmk7.com/forums/index.php?threads/dcc-retrofit.378431/
Verify the DCC Firmware you have, vs the version required from the 2020/2021 Arteon or Passat
This can be found under the module: 14 Wheel Dampening Electronics. You can flash to a new firmware (not supported on this thread, as there is risk involved with bricking your controller).
Unfortunately you cannot simply plug in an Arteon DCC controller as they are tied by VIN to a car. Going to a dealership won't help either, as according to VW, they will simply tell you that 5Q0907376B is the latest and greatest and 5Q0907376C won't work.
DCC parametrization that goes with this firmware
Verify the gateway and get proper versions in place, in a safe spot (GTI 6MT / DSG, R 6MT / DSG settings)?
3Q0907530Q and higher Gateways
This can be found under the module: 19 Gateway. The main value you are looking for is the software number.
Of course the dataset that you are going to update with:
- FPA dataset (Gateway dataset that holds the settings for your driving profiles) that enables the slider.

How-to document (this is key to piece together what needs to be done / missing information)
For my DCC Controller
Hardware - 5Q0907376A version H17 / Firmware - 5Q0907376B version 0121
For my Gateway
Hardware - 3Q09007530C version 518 / Firmware - 3Q0907530G version 5304
