Good on you, I always replaced oil much sooner in all our VW cars and in Tiguan I did the oil/filter change at 1,000km, and gues what? The engine survived too and it runs well without the need for oil top ups.

You can replace the washer on that drain plug but VW drain plug is not expensive. The washer is the steel one and easy way of removing it is just snipp it off with the diagonal cutters. If you buy the oil filter from somewhere else than VW dealer watch out, the oil filter could be made in China despite it is in Mahle, Mann Knecht box.
