Mercedes Sprinter T1N EGR Valve – Pierburg OEM | OM647 2.7L 5-Cylinder | #6461420119 (2004–2006)

DESCRIPTION:

The EGR valve on the T1N Sprinter's OM647 is one of the most well-documented failure points on the platform — and carbon buildup is almost always the cause. The valve begins to stick as deposits accumulate on the valve body and seat, causing it to malfunction in either the open or closed position. Cleaning can buy time, but once the solenoid starts failing under the increased load from buildup, replacement is the only reliable fix. This Pierburg OEM EGR valve for the OM647 2.7L 5-cylinder is a direct replacement that restores proper exhaust gas recirculation and clears the fault codes.

What This Part Does

The EGR valve recirculates a controlled portion of exhaust gases back into the intake manifold, reducing combustion temperatures and cutting NOx emissions. On the OM647, it's an electronically controlled valve that modulates flow based on engine load, temperature, and operating conditions. When it sticks open, the engine runs rough and loses power. When it sticks closed, emissions spike and fault codes appear. Either way, a failed valve needs to be addressed.

Common Symptoms of a Failing EGR Valve

• Rough or unstable idle
• Reduced power or sluggish throttle response
• Increased black or blue smoke from the exhaust
• Check engine light with EGR-related fault codes (P0400–P0408)
• Failed emissions test
