EGR Valve connecting hose

[mike2909]

The vehicle is a 2005 ML270 CDI. I am looking for a part number or the name of the hose that connects to the front of the egr valve. I have been on the phone to Mercedes parts department and they have emailed me the parts diagram but the part is not shown. I have tried to explain it and have emailed them the photos but they still can't help me,
Could anyone advise me the part number or name of the hose.? I would have thought Mercedes could do that from my description and photos .
Thank you in advance

Original part	A 163 501 45 82
Replaced by	A 163 501 61 82

There is a faded part number so illegible . Yes that is it indeed . Thanks very much . Are those parts diagrams available online?
