Yup, flush the oil system out with a few consecutive changes and (along with filter changes) until you don't find any trace of the contaminants.

Try switching to another oil - Shell Ultra Helix 5w40 is even worse than M1 0w40 IMHO and has no place in an aircooled engine. I will broaden the recommendation that basically any Porsche approved oil shouldn't be in your engine, especially a turbo! I'm not up on all the oils available in Europe, but you should be able to find Motul 300V, and their 15w50 would be an ideal choice, albeit expensive.
