I know this is old however it might help someone someday. There's no easy fix for this nor cheap, but if is done right will last another 10years or more :) What I've done, how and what else I should've done -remove door panel glue back whatever pieces are loose let it dry completely and apply some protection on the cardboard lower part - I used several thin layers of clearcoat applied with a soft brush - remove the vapor barrier from the door and clean the interior of the door as perfect as possible. - inspect drain plugs and replace any missing or damaged caps -reapply wax be generous especially on the lower part where it is known the door will rust -inspect wire harness and replace the insolation tape if needed - use same type as factory - textile black single side adessive. -clean all the plugs and apply contact corrosion protection spray use any brand automotive, no wd40 is not for that. -clean the vapor barrier and remove the black old goo aka butyl tape. I used same rags soaked in paint remover/ nitro thinner - this will be fun, the barrier holds well to this powerful solvent however it doesn't have to be spotless. - apply a new cord of butyl tape follow the old contour and while you unwrap the tape from the paper stretch it a little bit. Also put it on the 2 middle sections like e38s my eurospec e39 didn't have there from factory but you can clearly see from the pattern that it was designed to have. - route the electrical harness through-out the vapor barrier dedicated spots center it onto the door frame while you gently press it against door frame. Once it is correct centered apply increased pressure with your hand all around, cm by cm until the circle is completed twice. Don't forget the center pieces. No heat gun needed if temp is above 20C. In fact a hair drier is enough to pre heat the metal frame... - put back the door panel. Replace all broken clips with genuine ones only -new or reused Now what I should have done and I didn't from the start was to replace the windows cranes. After 1 year the cable snapped at right door and another year later on the left door the plastic upper roller cracked and the cable was tangled around and window jammed opened. So replace those cranes with original new ones while you're there. The motors were perfectly fine. All 4 doors will have this failure after 20 years so as a preventive action might not be a bad idea to do them all. If this happens at the front doors things will get very ugly very soon as Nat already explained. If carpet gets wet in front of the car left or right side another cause worth mention it here is the heat exchanger/ AC cabin radiator or its pipes broken, cracked or clogged - dashboard out. ugly stuff also...

I deal with this on my e39 and on other brands at work. If you make sure the door drains are clean and unobstructed it helps a lot. Water can still fill up the door and run over into the car, but it helps. Clean sunroof drains are very important. Great channel keep it up.
@francispowell1811

Yes, the door drains need to be cleaned periodically. I spray with WD40 as well and mist with light oil. I've had to clean the sunroof drains of crud, clean thoroughly and reattach the hose to the spout with a slight touch of black silicone then secured each with small black zip ties. The tension of the hose on the sunroof cassette spout goes over time and need the silicone and zip ties to remain secure. So far, so good. I no longer use the sunroof, as a preventative precaution.

I used to have an intermittent problem with my back passenger doors some times leaking rain water upon the carpet! Sometimes from the car wash also!!! I have place aluminum foil all the way across the door threshold on both sides! That stops the carpet from getting wet! Again the water leaking is an intermittent problem! Even when it rains or the car being washed it does not always leak water! By using the aluminum foil I have not had any water leaking into my carpet since I bought My BMW, it is a 2003 530ia with 137800 miles no codes or oil leaks , everything works! I maintain it by myself!

The only permanent fix is to instal a new genuine BMW vapour barrier with the butyl, it’s not too expensive from BMW and you will have around another 15 years of leak free service life by using the genuine parts. Do it right the first time ( with genuine parts) and there will be no comebacks on this job.

Now that I recall, the lawn guy sent a rock flying through my passenger window, and had safe light come out to fix it, only to realize the regulator went bad, and window would not stay up... jammed a screwdriver on the inside for a month until I had time to look at it.. water was shushing while driving, didnt know where it was coming from.. realized it was the door, carpets were soaked, didnt know at the time, cuz no1 like riding in the "old car" with dad.. took the sunroof cassette and headliner down, drains were connected, zip tied for my state of mind, blew some compressed air theough.. rained, same issue.. checked moisture barrier, resealed with removable 3M adhesive from home depot, as well as chaulk.. same issue, swishing returned.. drained out water from door for the final time. Left everything disassembled, rolled up windows, took a gallon of water, poured it above the door.. found the leak was infact the window (silver or black depending on your model) trim with squeegee.. wasn't repelling the fluids efficiently.. small gap where squeegee was completely off glass, realigned glass, took squeegee off, cleaned out leaves, soaked, wiped, took out bend, and mated to glass.. problem solved 👍

I think the key to any leak is to focus on actually fixing the leak. I have seen people rip up carpets etc and dry them out only to have the same leak come back. Just drilling a small hole or knocking out a bung or two solves the wetness under the carpet once the leak is fixed. Finding the actual leak if it's not one of the things in the video can get very hard.
@francispowell1811

It is that the drain holes in the door get blocked, coupled with a disintegration of the butylene over time, not that there is a leak, per se. The car is designed for the water to enter through trim as the base of the window, but then to flow through the six drain holes along the bottom of the doors. As preventative maintenance, it is wise to check the drain holes and reapply butylene periodically. However, drilling holes in the floor pan is a good backup measure, especially so as the electronic junction box of the e39 is located ahead of the passenger front seat on the floor pan. Keeping that dry is critical for any car that one plans to keep long-term.

The vapor barrier is a crap design and just putting tape on the outside is a poor fix. Water trickles down the barrier and will pool at the bottom where the Butyl rubber / tape is. I put a deflector on the seal internally at a higher point minimize the water reaching the bottom of the seal. Then applied new Butyl up to the lip of the metal door opening to remove the pooling area.
