I have had this in both my current Z4 and last car (Golf GT TDi) and both were rectified by removing the door seals and replacing them, making sure they were seated correctly. Must just be a leak coming through the seals....

I had this in a Golf and it turned out to be a part that was like a piece of cling film that covers the inside of the door below the window. I think the part cost a couple of quid!

it's called the vapor barrier (i come from a Golf as well! lol)

We call it the door membrane.

I had the exact same problem on mine.
1) water enters the door at the window and runs down the inside. Due to a detached membrane it was draining inside the car and not out the bottom of the door. Fitted new membrane
2) I put a 2mm hole through the door seal at the lowest point near the front so that and water that ran down the seal drained outside and did not pool.

No problems since

Could you show me a picture of the hole you drilled?

No - it's way too cold and dark out there today...lol

Simply follow the line of the seal down the front door until you reach the lowest point by the sill. IIRC there is already a small air hole in it at that point. I put a hole in there right through in the softest part of the seal so any water following that line went through the seal, outside and no inside.

^ yup there is a whole already but not at the lowest point where the water accumulates. so you drilled one from the top and one at the bottom? or only at the top then you let the water drip from the existing factory holes?

just curious, when driving fast in the rain, doesn't water from outside, gets pushed by the wind and goes up thru the holes and in your cabin?

You got it. Small vertical hole right through the seal. All I can say is that the 2 fixes together thave resulted in a dry floorwell for the last year regardless of washing, jetwash, floods and rain. IMHO the main fault was the membrane on the door being damaged. The hole was the final step.

yes it is the membrane that causes so much water to puddle and some flow from the a pillar down to the same point as well actually
