This seems to be a wear problem on these engines. Have seen a number of different ones on you tube. Watched VAG technic in Germany doing a number of V6 rebuilds. The 3.0t has been on the road in various iterations for over 10 years now, beginning in 2009 in the US. It is also evolution of the earlier and older 3.2. The b6 s4 issues were very very well documented before 10 years of age. If this was a real problem on the 3.0t, a quick google search would confirm the point. I would not let the timing chain "issue" change your opinion. Although there are some concerns with the TSB and it seems that the noise may return, the instances of actual failure are limited. Essentially, Audi has had timing chain challenges for better than a decade (on some engines it is nearly a wear item in the 90 - 120K mile range). 5 posts · Joined 2013. #1 · Apr 7, 2016. Hey guys, have an a5 3.2 that seems to have developed a pretty decent oil leak on both sides of my upper timing chain covers. It doesn't look too hard to pull them off and reseal them, but my question is are there torque specs for these covers? and can anyone recommend some good sealant. .
