Have a 01 ml320, with leaking sunroof drain on passenger side. Water leaking on to floor of passenger side via light under dash and fuse and relay compartment.
Open up the sunroof and try to unclog the drainage. You will see this from the inside of the ML by opening the whole sunroof and stickin your hear thru. On the drivers side you will see a drainage whole similar to the passenger side. Mine did the same thing and unclogged it with a straw. [email protected]
