Auxillary water pump location
Anybody know where the small aux water pump is located on a 221 2007 ?
Its the pump that circulates water through the heater core when in REST mode.

When using the REST mode it only gives heat for a min or two so I assume the pump is not running. Had similar issue with my 2003 220 and that was the problem with it. Aparently this pump is located in the same area.
