560sec No Heat

My 560 sec has quit blowing heat. Blower fine. Fuses fine. No smell of antifreeze. puzzled. will appreciate any help. thanks

Most likely the monovalve has failed. ~$30-$50 part, and 15 minutes to fix, if it is this.

For a illustrated walk through of replacing one, look at http://mbdieseldiy.tripod.com/monovalve.htm

For more active commentary on MB's, you might take a look at benzworld.org and mercedesshop.com

I hope this helps some!
