What is carbon buildup and why do European cars get it?

Carbon buildup is the accumulation of hardened oil and fuel deposits on the intake valves of direct-injection engines, a common issue on BMW, Audi, Volkswagen, and Mercedes turbo engines. Because these engines spray fuel directly into the cylinder instead of over the valves, there is no fuel washing the valves clean, so deposits build up over time and cause rough idle, misfires, hesitation, and lost power. The proven fix is walnut-shell blasting, which physically cleans the valves. At Motoro Cars, our ASE-certified technicians perform professional walnut blasting to restore lost performance and fuel economy. As an AAA-approved dealer alternative, we do this for less than the dealer charges. Periodic cleaning keeps direct-injection engines running strong.
