Hello,
Dealer told me it is carbon build up in rigth head. How do i clean this if posible, or did anyone ever get to fix this problem without spending big bucks at dealership. Acording to the KBB value they want to charge me half a car. So if any Mercedes Technician can help me out how to fix this in this economy I would apreciate. I just want to get my plates so i can drive the car. Anyone please help.

Thanks
Help me drive my mercedes i worked hard for it and now i can't drive it.
