I'm back with what I believe to be a meaningful update.
After 3 days of being told "tomorrow" I decided to re-flare the union myself. I bled the system like crazy and when I attempted the VCDS procedure again it never told me to open the bleeder valves. So I took a drive the brake pedal is vastly improved but there is still just a slight mush to the first bit of travel, and for some reason every time I get to the end of my drive way the pedal seems to be longer and lower than any other stop???
Any how, I steam cleaned the reservoir and the lines and made sure there was no fluid on anything and could easily identify a leak if there is one. I had a local car x willing to give it a 2nd look and they weren't able to find any leaks in the system.
I called VCDS today and chatted with them for a bit. Initially just to see why the system never told me to open the valves...
In the Touareg there actually is a 12v vacuum pump between the vacuum source and the booster to ensure that there is always sufficient vacuum and they believe this may be required here also due to the added volume of the booster. They also noted that the Touareg's do have a softer and notably lower pedal than the GTI to begin with so while I may improve the feel I'll likely never see the same firmness as I was able to achieve with the GTI booster and the TTRS MC. I'll let you all know if I take any additional steps to improve feel from here but as of now I'm in a really good place with this setup.
