Hi Guys, I current own a VW Golf 6 1.2TSI 66KW/88bhp variant. I've seen some of posts regarding 1.2 TSI camchain issues and what to look out for. I read one post titled "2013 1.2 TSI timing chain" saying that the chain design was revised in 2011. My car's production date was September 2011, and the car currently has about 75000km/46,000miles on the clock. Because of these known issues I'm starting to worry whether a timing chain problem may occur, even though I take care of the car with regular oil changes, service intervals etc. Since it seems that there are people who know a lot about the subject, I was wondering if anybody could tell me the month in 2011 which the timing chain was revised...just to have a piece of mind. Many thanks in advance
