Q5 Brake Problem PLEASE HELP
I have been dealing with a problem lately with my 2013 Audi Q5 3.0T. The brake pedal at first started to feel spongy. Days later it would go nearly to the floor while simultaneously activating the ABS and causing the pedal to buck like crazy. The only related code that was showing up was 'Brake Vacuum, Low Limit Exceeded'. It felt to me like a bad master cylinder, so I replaced that yesterday. I bled through all 4 corners and I'm still experiencing the same thing.
Can the ABS abnormally activating cause the pedal to go to the floor and nearly no stopping power???
And ideas on what to check next?
I'm kind of thinking that the low vacuum pressure code might be related to the fact that such a large volume of space is being compressed out of the booster, causing the vacuum system to be momentarily overwhelmed.
I'm kind of stuck without a car until I sort this out. Any help would be greatly appreciated!

@shane0926 I'd head over here to search if others have had similar issues: Q5/SQ5 MKI (8R) Discussion - AudiWorld Forums

Thanks, I will look more, but I've been searching the forums for hours now. No one seems to have the extreme pedal depression coexisting with the ABS spuriously activating.
