After rain inside of door shut where is meets dash is wet

[Tom_GGG]

Ive got a 09 v8v convertible.

I noticed that after some rain the inside of the door shut where is meets the leather of the dash seems to be soaking wet, see photo below. Is this normal ?

What can be done about it ?

Door or roof seal has either failed or is out of position.

This a picture from my last N430 which let in water whilst washing but it’s probably the same issue as yours. The window closure was adjusted and was partly successful, turns out a hidden rivet in the door frame was hitting the glass when it was performing its final seating on door closure. The dealer sorted the problem after discovering the real cause.
