Have you tried clicking on the "Buy Parts" link at the top of this page?


I just remembered that I replaced that very same hose on my S420, which should have the same engine as your car. You most likely need this hose:

P/N A 119 090 19 82

Which I got for $42 at the dealer.

I posted a thread about it on benzworld if you're interested:
