I ran into this about two years ago on my 2003 E500. The hot water valve under the hood, just in front of the firewall had malfunctioned. After it was replaced all was well.

When I get home this evening, I will pull the receipt and give you part numbers. The fix was covered under warranty so I do not have any prices.

The part is called the secondary heat shutoff valve

The part number is 211-832-00-84. This part is located under the wiper and cowl grill on the engine side of the firewall.

Good luck,

Randy B
