Mercedes EGR Valve - Genuine Mercedes 0021400060

Product Information

An Exhaust Gas Recirculation (EGR) valve is an emissions control component that recirculates a portion of the engine’s exhaust gases back into the intake manifold. By mixing exhaust with the air-fuel charge, it lowers combustion temperatures, reducing the formation of harmful nitrogen oxides (NOx) and improving efficiency under certain conditions. Modern vehicles may use electronically controlled EGR valves for precise operation.

• Rough idle or stalling, caused by the valve sticking open and letting in too much exhaust.
• Poor performance or hesitation, often from a clogged or stuck-closed valve restricting proper gas flow.
• Check Engine Light (CEL) with related fault codes (e.g., P0401 “EGR flow insufficient” or P0402 “excessive EGR flow”).

About Genuine Mercedes

You may not realize this, but the parts that make up your Mercedes-Benz are not necessarily manufactured by Mercedes-Benz. No cause for concern, as Mercedes-Benz designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Mercedes-Benz for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Mercedes-Benz parts box and find an OEM branded part inside, simply with the addition of a Mercedes-Benz logo.
