EGR valve mystery hose w163
04 ml500 ( w163 )
Changing out my egr valve and the replacement only come with 2 of the 3 hoses, and I need to replace the mystery hose (#3). I have searched high and low, and can not find a replacement or part number anywhere. I am attaching a photo for reference...the detached tube in my left hand is the culprit.

I need to replace this mystery hose.

Here are the hoses in question. You must also need a new gasket.
