Thank You Sir, I found the same problem with my 2011 ML350 and fixed it following your posting. Mine was like yours. Fluid level was fine but the pump was saturated with water held there by the sponge wrap brilliantly fitted around it. (What were they thinking) Cleaned it up, dried it out, sprayed with WD40 and after a few raps with a soft hammer, it works ! Thanks again for sharing this fix.
