VW OCI for the 2.0T is 5000 and then 10 000. I am not sure if you do 2 5000 miles intervals and then switch to 10, or if you just do the first at 5000 and then go to 10 000.
RS4, I know that you are very passionate about the BioLube oil and that you have evidence backing it up, but I am also certain that you would be able to go toe to toe with Audi (litigation wise) if you experienced any engine problems and they tried to blame it on oil.
RS4~$75 000
GTI ~ $25 000
Most people driving GTI do not have the time nor money to go to court if VW denies their coverage based on oil.
VW has been pretty outspoken about correct oil use, especially after the sludge issues they had to face.
My recommendation, maybe not the best for your engine, is to stick with 502 00 oil while in warranty. After that run whatever you like.
If you are really concerned about the wear, change the 502 00 oil every 3000, 5000 miles or whatever makes you happy.
