VW 511 should be fine. It's for "Gasoline engines with OPF" apparently, which is good because it means it will have been designed to reduce oil consumption, which is useful on TFSIs
I think it supersedes 502. 502 is, or was at least, for petrol turbo engines on fixed service intervals and 5W40.
I can't keep up with these constant changes but as above, platinum or platinum plus 5W40 will be OK.
