Direct Injection Intake Valve Carbon Buildup Issues
Is anyone having issues with this carbon buildup problem? What are you doing to clean them? All Panameras have DI, right?

every car site that has direct injection has tons of posts, I don t see this being an issue for a long time if at all for most of us. So if you loss 8 hp in ten years for example that s common.
My choice would be to wait till there is an issue and then just get it walnut blasted if I owned the car that long.
