I am somewhat sceptical if things are as straight forward as in the video. A friend of mine for the last 5 years and a VW mechanic at the largest European VW van Centre (Billie show in Reutte Austria) where I bought the van urges me to not to touch the system or "you will have big problems," even 10 mil overfill can cause expensive problems" he wrote from his vacation in another country. When he gets back I will clarify what he means by his warnings. No, he is not drawing me back to the dealership for a profit. I meet him often socially. That is why I wrote earlier that I am confused. I still have plenty of kms to go on what is left so waiting is not a problem.
