That is the same manufacturer and 2.0T engine I owned for 10years prior to the JLU v6. The problem with DI carbon buildup did not occur until 7+ years on my Audi. I ran ONLY top tier premium fuel and took great care of the vehicle/engine.I guess that will depend a bit on the engine design. I put 140K miles on an Audi 2.0T direct injected motor in ~ 3.5 years and had zero issues with carbon buildup.
So this is only a concern for those who plan to drive the DI vehicle for many years. Let's hope the FCA designed 2.0T does not have the same issues as the Audi 2.0T.
Again, it takes years for the carbon buildup to cause a problem.
