I recently bought a seat gap Filler for my Brown interior Q8. I just wanted to share the link as the color matched perfectly and the features are good too.
I didn't want to use the center console to store my phone or charge it, so this is a great solution as I can just place in the ouch (going to try to affix a magsafe charger inside).
I do not know about other colors, but this one worked great.
