Water coming from base of passenger side rear door
Hi all,
I have booked my F10 to be looked at next week. On Friday, it rained over night. On Saturday morning my daughter opened the rear door and lots of water came pouring from the bottom of the door. There was approximately 1 litre I would say. I felt underneath and there is a drain hole - atleast that is what it feels like - it may not be. I prised the plastic door fitting slightly, just 1 to 2mm with my fingers - barely any pressure and more water came out. It seems that water has found it's way inside the door cavity. The dealer had no problem booking the car to be looked at, as a warranty issue (car will be 3 years in November this year). Does anyone have experience of this? Is it likely that the window seal has failed? Thanks - cheers ... |

Water is supposed to get into the doors, there is no "window seal" that can keep it out. It's also supposed to get back out so you shouldn't have an accumulation like you saw.
When stationary, my E39 would hold on to some water in the back doors until they were opened but not 1L. It's a common problem with all kinds of BMW models for decades that vapour barrier glue inside the door will let go and water will start seeping onto the carpets from behind the door trim. You're under warranty, it's not normal, just get the dealer to take care of it. But know that water is supposed to get inside the door (and get back out). |

Though, I wasn't in cognizance to how common an issue this was for most BMW vehicles as most of my friends and acquaintances never discussed such factors, so thanks. |

I was in Vegas when it was 118 degrees and some of that yellow "glue" (more like a hardened "oil" that I see in the little crevice holes of my car) puked out of a tiny hole at the bottom of my inner trunk lid. It was a pain to clean off due to how oily it was and the little trail it left left some oxidation on my bumper (can't really see it but it looks like the surface-imprint i.e slight fade where it was that you see from bird crap).

An important point is that it's normal to have INCHES of water in the doors at some times (heavy rain, car washes). This barrier keeps it out of the interior while it works its way out of the door drains. |

In and back - approx. 5 hour turn around : vapour barrier glue compromised in some way. They have replaced this, under warranty. Service rep. said to monitor the door, in case it happens again. Another seal that goes around the whole door had some how slipped out of place and interfered with the vapour barrier.
Thanks to all for the replies. |

Problem occurred again. Same door. Annoying.
So I booked it in again - 7 hour turn around - additional parts replaced this time. Hopefully they have resolved it now. |

Vapour barrier had come away in the lower section, (lower curved section in the picture of my door). Only takes a small leak, as water can sit between the metal and the barrier, so continually has a 'feed' when raining. I used a heavy duty mastic. Eased off the barrier, used a hot air gun to ensure it was soft, (don't overheat) and removed a section of contaminated mastic. Added new mastic in the area that had become contaminated. With it warm, the original mastic will stick again. |
