Carbon Buildup in European Vehicles

What Is Carbon Buildup?

Carbon buildup is mainly a problem with modern vehicles, specifically European vehicles like Audi, Volkswagen, BMW, etc., with direct-injection fuel systems. When your engine burns the fuel and air in the combustion chamber, it releases tons of fumes or waste byproducts in the form of smoke and carbon. While most of it gets converted and transported out of your vehicle, some of it lingers and becomes what is known as carbon deposits. The more fuel you burn, the more these deposits will develop. 

Carbon deposits can be found in many places including the combustion chamber, intake valve, pistons, throttle body, cylinder head valves, fuel injector nozzles, and more. Eventually, it can cause more significant problems like restricting airflow to the engine.

What are the Symptoms of Carbon Buildup?

You can tell if your European vehicle has an excessive amount of carbon deposits by the following signs:

  • Rough Idling Or Engine Vibrations
  • Jerking Or Surging At Stops
  • Engine Misfires
  • Decreased Acceleration
  • Black Exhaust Smoke
  • Check Engine Light Comes On
