I have a 99 Ml430 with a code P0443. I know a purge valve needs replaced but I was told there are a couple on the car. Does anyone know which one needs replaced or how to find out which one needs replaced?

 

there is only 1 purge valve. its drivers side under the hood near your throttle cable and throttle position sensor. its beside the engine, it has a rubber thing around it to hold it to the bracket. will have 2 rubber hoses or plastic hoses attached to it and also an electrical plug.

 

Do you know a place besides Mercedes where I can get the purge valve?
