mercedes dealer seems to cause new problem each time 99 ml goes in. Question......i notice now at slow speeds(when brake) I now hear a "sloshing" on right side from under car...no visible wetness inside....dealer repaired my sunroof track recently....i wouldn't think it was gas tank?? any ideas???? HELP.....TG for this forum

 

The last time I had an ML with a sloshing noise, it ended up being water trapped inside the step bars. Taking the end caps off let the water out and fixed the problem. Of course, if you don't have the step bars, I don't know where to lead you.

 

I now see dripping from under rocker pannel.(plug?)....as the truck has been sitting in one spot......it is water

 

Yes, it's water. What's happened is that you drain plug by the rockers are plugged. Unplug the drain plug (you can actually pull the rubber plug out and replace it after draining) and you'll be fine.
