I am seeing the P00AF/P2563 codes, too. My car is a 2015 GTI PZEV with 84k miles, but I live in NH. The dealer wasn't aware of the extended warranty, so am not sure if it applies here. What state are you in? Thx
I see you found the other forum I had posted in about this. I did post some links in there too with a little more info.
