An awesome aspect of German automobiles is that most models utilize a Fuel Stratified Injection (FSI) engine. As suggested in its name, fuel is injected directly into the combustion chamber where it combines with the air entering from the intake manifold. The mixture is compressed and causes a spark that amplifies horsepower. Unfortunately, FSI engine carbon buildup is commonplace. Excess carbon causes restricted airflow and loss of power.
Symptoms of Carbon Buildup
If you notice signs of carbon buildup, then bring your vehicle to an Audi & VW repair center. Typical symptoms include:
- Lack of engine response
- Lag in acceleration
- Lack of response when hitting the gas pedal
- Check engine light frequently flashing on
- Misfiring, which becomes noticeable when the engine revving noise sounds erratic
