It has the updated tensioner. When the intake manifold was handled under warranty, the VW techs said the intake valves looked pretty clean, so I guess the carbon cleaning has already been done. Chain stretch is at 2.75°, so I'll be good for a little while.
Thanks for the update. I have a buddy who is an Audi tech so he looked up the service history for the one I'm considering. In 50k miles, it's had intake manifold, water pump, pcv, and fuel injectors replaced. Tensioner and chain are original.
On one hand, I'm glad to see the prior owner was proactive with maintenance, but on the other hand, I'm now having second thoughts as if it needed this kind of maintenance/repair in only 50k miles, what's it going to be like over the next 100k???
