Carbon Cleaning Sale
The build-up that forms under normal operation can decrease engine power within a relatively low amount of milage. Most anecdotal evidence shows that when the intake valves are cleaned, engine returns to spec-rated horsepower and torque. This build-up is thought to affect power in as little as 10,000 miles though few people have routinely removed their intake manifolds to document the build-up progress.
A wide-range of variables have been included in reports of build-up. A common theme is that this occurs despite tier 1 fuel and Audi recommended oils. Reports have also come in from all over the world, suggesting it’s not localized to any particular region’s fuel, environment or emission standards.
Severe cases of build-up can potentially trip misfire CEL codes though in most cases, the car simply produces less power and does not indicate malfunction. Those that have cleaned their intake manifolds explain a burst of acceleration under WOT at 6k RPMs (2nd gear)(applies to RS4/R8 4.2). Dyno results for affected cars seem to be anywhere up to 40hp below quoted stock HP on the 4.2 V8 FSI engine.
To remove build-up, a physical cleaning of the intake valves and vanes using Walnut media blasting has shown to be able to completely remove the carbon of which Audi will not warranty unless there are continual misfires occurring.
