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.
https://github.com/jilleb/MQB-FPA and of course it's wiki will get you to where you want to go: https://github.com/jilleb/MQB-FPA/wiki

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

Wtf I never even knew this was possible. It would be great to have start to finish walkthrough of how to do all this.

I think this is all the updating I am going to do for now, I need to pull my front passenger strut assembly to replace the mounting kit, since I was too anxious to get things done instead of waiting for parts to arrive...then will figure out the DCC controller and tackle the Gateway after. Time for me is a bit of an issue but will pick away at it

Appreciate the write up and without a doubt @Chillout and @Cuzoe should get recognition for helping so many of us do this. There is a Skoda thread here:

https://www.briskoda.net/forums/topic/506152-dcc-slider-adjustment-option-mod/page/1/

That covers the path we took. I had the help of a VAG coding wizard through all of it on my 2017 Skoda Superb 4x4 206TSI, (which for anyone in the US is essentially the drivetrain of a Mk7 Golf R in a large wagon). I had a 5Q0 gateway initially and most people who have completed this used a 3Q0 gateway so we swapped that to start.

Here is the overall sequence of events that was encountered and followed:

  • Swapped to 3Q0907530C gateway with software 4287.
  • Removed Component Protection and restored FEC using ODIS online.
  • Upgraded gateway software to 3Q0907530AC sw 4388 with ODIS Engineering.
  • Applied dataset 3Q0907530AC_Superb_3.xml
  • Extracted data from the XML file and modified to add 15 increment slider using the 'Full Example for DCC Index C with slider' on the GitHub page using the addresses given in the drive2 link and pulling the hex values from the GitHub example.
  • Note that the data for 'remember after reset' doesn't line up with the drive2 example (nor does the slider example, but this is more obvious from the github example as the data is just 0-15) so I copied the values from the GitHub example manually from 0x2E0-0x2EF.
  • Applied modified FPA data using ODIS Engineering.
  • Flashed DCC controller to 5Q0907367C and applied Passat dataset.
End result:

Following the mod, I thought it might be beneficial to conduct a DCC calibration given the car now uses a new dataset in the DCC module. Used a hoist today to do that using VCDS. Result is it feels like the increased firmness has calmed slightly and the compression damping over small bumps is now smoothed giving a slightly less busy ride in all modes.

DCC calibration procedure using VCDS (this is essentially a copy/paste of @Cuzoe 's instruction) :
  • Adaptation (basic settings) should be the same process on any car.
  • Vehicle on jacks or hoist with full droop (all four wheels hanging),
  • Module 14 Damping Electronics... Security Access 20103 (not required for my case, VCDS had already input code).
  • Go into Basic Settings and
  • Select the calibration from the dropdown menu and press Go.
It will only run if the level sensors are in the proper range. The field should say "Completed Successfully" or something similar and that's it. It essentially zero's the suspension like when you zero a scale and it took literally 1 second to complete on my car.

NOTE: Your car may drop down to the ground and look like it's now an SUV. The DCC valves appear to be fully closed and may hold the car up very high. Don't worry about that, the car returns to normal height as soon as you put it into gear and roll away.
