Frequently Asked Questions

MQB Evo vehicles store ambient interior lighting configuration in a binary dataset (DA_009_7206) that lives in the body control module. This dataset defines two color palettes: one for the actual LED strips (LIN bus) and one for the color swatches shown in your infotainment screen. This tool lets you edit those color palettes and save a modified dataset that you can flash back to your car.

  1. Upload your own dataset to the tool, or pick one of the example datasets as a base
  2. Make changes
  3. Save the file
  4. Flash the dataset with VCP or ODIS to your car*
  5. Enjoy the changes.

*If you don't know how to flash a dataset, please refer to the manual of your favorite tool (like VCP or ODIS).

It's not possible to "download" the dataset from your car. Instead, you can look in the list of example datasets for your car type and brand. Don't worry if you don't find your specific car. Most datasets can be used on multiple cars. Incompatibilities can occur when you select a dataset that was meant for a car with a different hardware setup than yours, but your car will not be bricked. Just flash another one and try again.

If you have access to ODIS Online, you can get the exact same dataset for your car. ODIS saves the datasets here during parametrisations:

C:\Program Files (x86)\Offboard_Diagnostic_Information_System_Service\configuration\org.eclipse.osgi\bundles\114\data\dms2\

You can also find the dataset as a .xml file inside the ODIS Engineering project folder for your car. Look for a file named DA_009_7206_*.xml. This tool accepts both raw .bin files and those XML files directly.

The purple color originally appeared because of a bug and a hardware limitation. On early Leon MK4 models, a factory reset could cause the ambient lighting to turn purple. The reason was that the value sent to the LEDs was #000000 (pure black). For technical reasons, the LEDs render that value as a shade of purple instead.

On later models, this same color became part of the official onboard palette, even though the system was still effectively just sending zeroes as color data.

To get purple: set the LIN color to #000000 (pure black). The LED hardware will render it as purple.
