I would like to have someone perform a carbon cleaning of my audi s6.

Just did this myself on 2008 S6. Concept us same for 2009. Buy a can of Berryman's combustion chamber cleaner. Really simple just follow instructions. Don't freak out. Car will smoke/ steam a lot out of exhaust pipes when first driving after cleaning. Supposed to do this. It clears up within 5 mins. Can remember if 2009 is turbo or supercharged. Read cautions on can. They suggest NOT using on turbo or super charged cars.
