Carbon build up covered?

Hi, is carbon build up covered by the factory warranty? Will the dealer clean it for me? Thanks.

They will sell fuel clean up every time you go for service.

I heard redlining will solve the problem, true?

Nope (at least not to my knowledge), only way to properly clean out the carbon from the intakes is to have the intake manifold removed and have it walnut blasted. A big problem with DI engines!

Apparently the Audi's and VW's are notoriously affected by this with all of their DI engines too!
