Hi, guys, for the first time in ages we've both been out in the car, noticed some white marks on the near side front door mat, when I looked closer the floor beneath it was absolutely sodden. Looks like a leak right at the bottom of the door seal, anyone else had similar issues? I've also noticed the drivers seatbelt is starting to fray along one side, again, anyone had similar? I'm hoping they'll be covered under warranty, had the car literally 12 months yesterday, 19 plate.

That's unfortunate. Can't say I have had those issues & they should be sorted under warranty for sure.

Hope it get's sorted quickly

Hi!

I had a similar issue, fixed under warranty. Check out my thread, hope it helps:

Thanks, it looks like mine is leaking in a similar place, albeit on the opposite side. Will call dealer, see what they have to say.

Good luck with the dealer! Looks like It may be the same issue.

I found a picture of the door inside panel, this big black piece of plastic has a seal around the edge. In my case the seal at the bottom edge was broken and the entire panel had to be replaced. Now everything is fine.

By the way, if there was a faulty batch of those panels, or some assembly problems I wonder how many people have this issue but haven't discovered it yet. It took me a couple of months until I noticed a wet carpet under a floor mat!

Definitely looks like a vapour barrier failure.

We've had vapour barrier failures, for generations of models, where the barrier becomes detached for a few millimetres or more.

You have had the car a year...

Have you by any chance parked a lot (over last summer) with the sun on the door that has failed? I know from my own experience that can be a cause, had the same issue on 5 doors over the past 18 years. All on doors that have a lot of direct summer sun on them. I believe the extra heat softens the bonding and any stress in the barrier pulls the joint.

Cheeky.

The secret of the Highlands, (don't tell anyone), we have some hot sunny days.

That and spectacular scenery 😎

Car was used fairly regularly over summer whilst I was working so not left for a prolonged amount of time. On the plus side there isn't any smell of dampness. It's due a service in May so going to see if it can be serviced a bit earlier in late April, I've a week off booked, and sort it out then. No one had any issues with the seatbelt?

A leaking vapour barrier can usually be identified with water coming down and out from under the door, between the metal door frame and the door card.

A bit like in the image below, from my 540i.

I think that may be my issue, will try and call them, see what they have to say. Thanks.

[machman767]

Just had a thought but decided to run it here first, think I won't bother but is it worth calling BMW Assist or is it mainly for more serious incidents?

[machman767]

So booked in for 26th April, they want it for a couple of days to investigate leak, fix then check again. Booked a car, see what delights I get.

I think I’ve got this issue.

Did you get yours fixed in the end?

[machman767]

Hi, it did get sorted, they replaced the seal, the carpet on the near side and the sub, apparently it had got wet. Seatbelt was replaced too, no issues.

Cheers.

Any reason behind why it happened?

[machman767]

I think it was as HighlandPete said, batch of faulty seals. Shouldn't be an issue to get sorted under warranty.
