Thanks Mark.all the wires going to it are brown. Brown = chassis ground.
Ah, I see what you mean. Thanks for the update. The hope is that we can identify ALL the 'objects' in the E39 M54 engine bay.that looks like a starter solenoid with the larger round case below the actual starter motor.
So, I 'assume' this is the 'purge valve' from the prior discussion; and, it may be worth noting the picture itself was saved as 'breather valve'.It's located behind the reservoir for the power steering and under the intake manifold--one hose coming in and one going out--there will also be an electrical hook up on it--when I had this code come up I cleared it by tightening the gas cap on the car and that worked for awhile--then I removed the rubber 0 ring on the gas cap and on the 0 ring there on the outer edge of it I filled that area with black Permatex gasket maker and let it sit up overnight. By doing this -it made a tighter seal around the cap.. Year later my purge valve did fail and need replacing at that time though.
Hope that helps
Are they not the same?How does the one in the back work?
