Standard Ignition Vapor Canister Purge Solenoid,Vapor Canister Purge Valve P/N:CP817
Keep your Mercedes-Benz EVAP system breathing correctly with the Standard Ignition Vapor Canister Purge Solenoid / Canister Vent Solenoid (CVS47). It drops in as a direct-fit replacement across a broad range of Mercedes-Benz models, including the 2002-2009 C230, 2001-2005 C240, 2003-2009 E320, 2000-2006 S500, 2005-2016 SLK350 and 2020-2021 GLC300 — see the Buyer's Guide tab for the full 56-application list. This solenoid meets OE specifications and helps maintain proper emission controls by managing the flow of fresh air into the fuel vapor canister.
If a failed vent solenoid is the cause of an EVAP trouble code or an illuminated check-engine light, this unit replaces it — diagnose the fault first, since those codes can have other causes. This part is cataloged as a Vapor Canister Purge Solenoid/Valve and described by the manufacturer as a Canister Vent Solenoid, so it is listed under both names.
