[VW Mk5 2.0T FSI (BPY) intake valve carbon cleaning service before and after.]
Intake Valve Carbon Cleaning
The direct fuel injection systems found in various VAG TFSI and TSI engines causes large amounts of carbon to build up on the intake valves resulting in starved performance and excessive fuel consumption. Cleaning the intake valves requires removing the intake manifold, using a walnut shell media blaster, manually removing carbon from the valves and servicing the fuel injectors using OEM parts and tools. We recommend having this service performed every 40k miles.
