2017 Audi A6 3.0T - Coolant color in reservoir

[Touareggg]

Hi all,

I just did a coolant bleed after cleaning my supercharger intercoolers and I open the coolant reservoir and I see a brown and pink color (g12evo). Is the brown color what I think it is? Gaskets were replaced <400miles ago. Forbidden chocolate milk? Or is it just a color effect from the bottom of the reservoir? Or am I paranoid?

I’ll see if I can attach a video

I did top off the coolant and I still see the color difference. Now I think it’s just a color reflection, i hope so. The videos expire in 2 days so lmk when that happens.

Maybe remove the coolant tank and clean it or get a new one
