96 C280 Trunk Leak
 

Hi, I have a difficult to locate leak in the drivers side trunk well just below the left brake light assembly and at the most rear and low point of the trunk. The leak does not appear to be coming from the tail light seal and the carpet is not wet. Quite a bit of water accumulates in this well that is under the light assembly.

There is no leak in the right side well under the right tail light assembly.

Is there a common mode problem that results in standing water in this well location?

Thanks

I would check to see if there are any drain tubes that are blocked.

There is a stud from the bumber bracket that is in that area. Perhaps the nut is missing or loose and water is traveling along the stud into the trunk.
