V6 TDI front main seal leak

Anyone else with a V6 TDI with a leaky front main seal? Specifically CNRB engines?

I finally got under my new-to-me 2013 and noticed the front of the engine below crank level is quite grimy.. best I can tell without removing all of the boost piping is that it's the front main seal. I'm going to start with cleaning everything up as best I can to make the leak more visible. nothing quite dripping, just a thick coat of oil and dirt. It does have a fair number of miles so far, but I am a little OCD and prefer to work on a clean engine so I'll be getting to the bottom of it.

Had to have mine replaced earlier this year. It started leaking right after (1-2 days) my water pump was replaced under warranty (74,000 mile). Diagnosed as front crankshaft oil seal. Took them a few hours to replace. The part is cheap, under $100. All under powertrain warranty (10yr/100K).
