Water sloshing behind dash
Hi all
new to forum with an interesting problem. My car sat out in heavy rain for 2 days in driveway at a slight 5 degree down angle- nose down. Drove it next day and heard a sloshing between firewall and directly behind dash. No water inside. Not rockers . Not doors. Wondering how many drains up front that may be clogged. All that i could immediately find clear.Nothing under cowling. Poured 4 L down and drainage seemed fine. No backup. Nothing to do with evaporation codensor- that would be more a hiss
WHERE IS THE WATER?

See here: https://mbworld.org/forums/sl-class-r230/637085-06-sl500-r230-hood-vent-grille-question.html
There is a drain hole under the vent. If it is clogged, water will be collecting right where you hear it sloshing.

Had this, to get to the drain hole you need to remove the wheel arch liner and clear the grommet from within the arch. The drain exit is actually through an aperture in the arch liner itself.
