    Water Leak on passenger floor 2008 E65

    Does anyone have a definitive fix for this? The roof vents are not leaking, The door seals appear to be valid. This problem seems to be really exacerbated by snow collecting in the windshield wiper well. Are there vents or drains there or do you think this is a problem with the Micro-filter drain?
    Any help would be appreciated. I am ruining the interior on this beautiful E65.
    Thank you in advance.

    The vapor barrier under the door panel or the sunroof drains these are the most common, there certern,y would be drains in the compartments along the fire wall get a flashed light and look around check micro filter housings also

    Poorly installed windshields can cause a leak, too.

    This was right side microfilter drain on my e65. Full of dirt and leaves. Drivers side was clean. It's easy to check so I would do it first.

    Did this solve the problem? I’m having the same issue.

    You just have to check it and clean it from time to time.
