Detailed Description

Dorman 911-855 is designed for Mercedes-Benz evaporative control systems where the purge valve regulates fuel vapor flow from the charcoal canister into the engine intake. When the original valve sticks, leaks, or fails electrically, the system can set emissions-related faults and affect drivability. This replacement purge valve restores the intended connection and function for the listed vehicles, including 2006-2013 Mercedes-Benz E350, 2010-2011 Mercedes-Benz E550, 2010-2011 Mercedes-Benz E63 AMG, and 2013-2019 Mercedes-Benz SL65 AMG. This part cross-references Genuine 2124702493 and Standard Ignition CP580, CP670 for the same application.

What It Helps Fix

• Check engine light related to evaporative emissions faults
• Fuel vapor leakage from a worn or stuck purge valve
• Rough idle or drivability issues tied to purge control problems
• Failed emissions inspection caused by EVAP system malfunction
• Hard starting or incorrect purge operation after valve failure

Installation Notes and Tips

Verify connector style, vacuum port size, and vehicle application before installation. The valve uses two vacuum connectors and a plastic housing, so transfer and routing should match the original layout on the vehicle. For best results, inspect nearby EVAP hoses and electrical connections for cracks, looseness, or contamination before installing the new purge valve. Fits 2006-2013 Mercedes-Benz E350, N/A.
