2004 E320 Sunroof Drain Leak
Added: I tracked down the leak further. I partially removed the covering for the A pillar, it's NOT coming off easy so I only opened it slightly....... afraid it might snap.
It exposed enough to see that the metal drain pipe (in the A pillar) was fine and the leak is apparently near the roof drain itself. I need to remove the inside pillar covering completely along with the headliner to completely expose the area.
Anyone have any hints or instructions I want to proceed cautiously to avoid causing more damage finding the source of the leak.
