Audi A6/A7 (C7 & C7.5) 3.0t Supercharger Belt & Serpentine Belt Replacement

This was done on my 2012 Audi A6 3.0t. It has 150,000 miles, and I have had it since 90,000 miles. This is the first time I have done these belt replacements on this car, and I’m not sure if the previous owner had them changed. Either way it was time to change them. I feel like a good interval to change them is every 75,000 miles.
