One problem related to timing tensioner has been reported for the 2013 Volkswagen GTI. The most recently reported issues are listed below.
My car's engine makes a ticking sound when I start it and when it's in idle. I was told that it could be the timing chain tensioner, since there have been issues with that with the 2013 models. I don't want to wait until my engine is ruined. Timing chain tensioner should not be going bad or showing symptoms with only 71,500 miles yet. I can't show you pictures, since it is hard to remove the cap covering the timing chain.
