Can anyone help me out and tell me what part it is that I previously posted a picture of? I go to Mercedes benz and drive 50 minutes and they tell me that they cant help me without the Vin#. SO I get the Vin# and drive back and guess what HE AGAIN cant help me out. God forbid they take a minute to pull up the pages that tthis part may be on. I love the parts guys who either hate their jobs or are just plain lazy. I felt like grabbing his head and banging it on the side of the computer.

This part is called a recirculator pump and it has two posts on it. The connectors that attach to these two post have corroded away. I had to order two news one for $4. Does anyone think that this may be the reason the computer is throwing out the P)200 code?
