If that was mine I would be buying some brake cleaner, spray it all over there as it simply removes all the oil with no elbow grease needed then check it again a week later to find exact location of the leaks.Please keep me upto date on the cause when you find out. Seen quite a few leak from the rear main seal now Bit of info for others.http://shopdap.com/rear-main-seal-failure-on-vw-and-audi-2-0t-tsi-engines/
Had the diverter valve out today and it all looked as new so that will stay in. I've got a 'G' revision diaphragm type, I'm aware there were problems with the diaphragms on the 'C' revision so a lot of people changed to the 'D' piston type. Not sure if there'd be any benefit going from a G to a D though. Ordered a new PCV valve 06H 103 495 AD (£78.20) and breather pipe 06J 103 213 E (£22.40) which it's advised to change as well due to the likelihood of broken tabs https://www.youtube.com/watch?v=hQEciqR1ST8. Next day delivery so will be able to fit them tomorrow.
