For the second time I heard water sloshing about in the rocker panels of my
1998 E320. The rubber drain plugs were blocked again - when I poked all
four of them out with a pencil about a gallon or more of water ran out both
sides. My mechanic said cut the holes in the rubber bungs larger. Who
designed this POS? My old 190E never played submarine!
There is something inside the door that is blocking the holes. Only cure is
to remove the door panel and cleaning out the inside cavity of the door.
Had this problem before on other cars.
