Mercedes-Benz C 240 Engine Problems
Your Mercedes-Benz C 240's engine is your vehicle's beating heart, responsible for converting your car's fuel energy to torque, which in turn moves pistons and cylinders that cause your wheels to move. As fuel burns, the internal combustion engine expands, resulting in more or less power depending on driving conditions. Your engine is sensitive and it is important to monitor its health. Here are some common problems that can keep your engine from running at its best.
- Dirty fuel injectors
- Damaged fuel pumps
- Damaged Oxygen Sensors
Each of these problems can affect your engine in different ways. Another thing to always look out for is if your engine is sputtering.
