I posted on BenzWorld, but I figured I'd try here, too.
The coolant line that comes out the bottom of the EGR valve on my '05 E320 CDI has sprung a leak. I can't find it by itself on the parts fiche, and the dealer says they can't figure out how to search for it either.

If anyone has had one go bad or has an extra sitting around or a source or whatever, please let me know.

Thanks, guys.
