EGR Valves & Parts for Mercedes-Benz C220

With their Classic, Elegance, Avantgarde, and AMG variations of the C220 CDI, Mercedes-Benz has created an iconic car with the C-Class. The Mercedes-Benz C Class uses an EGR system to reduce the chances of backfire and internal combustion, which can extend the life and performance of this sedan. When it comes time to replace the EGR valve and its parts, it’s important to know what changing out this component entails.

EGR stands for an exhaust gas recirculation system. The EGR valves & parts for Mercedes-Benz C220 are specifically designed to recirculate some of the exhaust gas back into the cylinders of your C Class vehicle so that the possibility of spontaneous combustion inside the car’s components is reduced. These systems provide this benefit by using the expended nitrous oxide and carbon monoxide to reduce the internal temperature inside the combustion chamber.

Typically, when the EGR valve on your vehicle is malfunctioning, you’ll get a check engine light on your Mercedes-Benz C Class. While this indicator can be caused by a wide variety of problems, you can narrow the issue down by reading the codes via the 16-pin OBD2 onboard diagnostics port on your Mercedes-Benz C Class.

Simply remove the cap and insert the 16-pin connector of your scanning device in order to get a diagnostic code for your vehicle. If you get a P0400 code, then your EGR system is having problems. Remember, when you’re getting the codes that the ignition of the car must be on, so ensure that you’ve engaged the parking brake.

The EGR system of your C-Class has five very important components. These include:

• Control valve: This component is very important for regulating the flow of cooling nitrous and carbon monoxide gasses. This part of your Mercedes uses a pintle valve and a valve diaphragm to ensure the gas input is measured correctly.
• Exhaust gas temperature sensor: Since the EGR system cools the internal combustion chamber of your C-Class, this sensor measures the gas temperature versus parameters stored in the vehicle’s memory.
• Vacuum modulator: The vacuum signal of the EGR system has to be precisely controlled, and this component ensures that the pressure is precisely modulated so that there isn’t an overflow or underflow of the gasses.
• Electronic engine control computers: This part is what enables the car to trigger the check engine light when the fault detection system notices an issue. When this appears in your C220 CDI or other C-Class Mercedes-Benz, running a diagnostic will generate the P0400 code.
• Vacuum change-over valve: If there are conditions that can cause trouble for the EGR system of your Mercedes-Benz C Class, the vacuum change-over valve will actually inhibit the system in order to protect it from damage. This system works in conjunction with the vacuum modulator.

The Mercedes-Benz BlueEFFICIENCY system is designed to reduce consumption in the transmission and engine of your C220 and C220 CDI automobile. As a result, these BlueEFFICIENCY vehicles use less fuel, which helps protect the environment.
