My little brothers 2010 Jetta 2.0t TSI is throwing a code p0016. Takes a second to start & has a really rough idle but will drive normal under load. I've read a bunch that the timing chain tensioner is a common failure for the first gen TSI.
Just curious if anyone else has ever dealt with this? I couldn't find any solid answers after searching a ton of threads on Vortex. I'd like any advice before I tear into it to see if the tensioner is failed. Thanks!
