How to Bleed your 3.0T Coolant System

This is our DIY on doing a full manual bleed on an Audi 3.0T supercharged engine (C7 A6/A7, B8/B8.5 S4 & S5, & SQ5). There are a few different schools of thought on this, but from my research this is the most comprehensive way to insure you get all of the air out of your coolant system. This method doesn't use any specialty tools that you have to purchase.

I showed how to bleed from every available bleed port, but keep in mind you may not have to bleed the heater core depending on your coolant loss from whatever job you were doing. Having said that, if you do bleed the heater core, I highly suggest removing the strut brace to have easy access to the heater core bleed port.
