Hello all,

Opened the hood the other day to change the EGR to a new one. That was successful. After a test lap around the block I re-opened the hood to notice the part in the picture making a buzzing noise.

It sounded like its a pump and that it was cavitating. Is this a bad thing... I guess so? It stopped after a few minutes.

Can some one please let me know what this is and if the buzzing is something to worry about so I can get a new one.

thanks J
