P 0400 EGR location

A couple days ago my check engine light came on and i finally got a chance to run the codes today and got P0400 Exhaust Gas Recirculation Flow Malfunction. I am not sure where the valve is, Can someone please point out where to find the EGR valve.

Thanks
Marc

Its on the passenger rear corner of the engine. Replace the valve and pipe. The pipe usually plugs up.

I have a Mercedes C280 1995 AMG series and recently have had same issue with error code PO400. Where is the location for this model and what procedure do I follow to make sure its not just a faulty rubber hose? Thanks.

(Just figured it out looking at the part on Autohaus.) However, my next question is are there any gaskets I would need to replace when removing the EGR to disassemble for cleaning or replacement?
