Guys its very simple. The rubber seal at the top corners of the driver and passenger doors has a gap under it when the windows are rolled up. If you put a folded up piece of paper in the interior corners while driving all of the "wind noise" that sounds like an open window is gone. I'll be going to the dealership to shown them and ask how they want to fix it.

Ill try to get a pic for you today.

I may be in the minority, and maybe it's because I have a MY2015, but the wind noise is almost non-existent unless I pay attention. Coming from a 2011 E90 it's like night and day.

The turbo drone on the other hand...

Does you rubber seal have a gap like I show in the video above?

Wind and tire noise is there for sure, on all F30s. How much one perceives it or is bothered by it, that's a different matter.

Here is the test that passed with flying colors. With the SIB for the windshield trim and somehow fixing these moldings, there will be minimal wind noise.

Cool, ill try this today.

BTW what is the SIB number?

The SIB he mentioned was 51 04 13.

The parts installed were:

51 13 7 321 818 B1-Clip (Qty 10)
51 31 7 258 187 B1-Drip moulding, left (1)
51 31 7 258 188 B1-Drip moulding, right (1)

Mine had that gap on both the driver and passenger windows when first delivered. Dealer fixed it, but the noise wasn't really reduced very much for me.

I mentioned the SIB for the windshield trim and they refused to install it; they said there was nothing wrong with mine.

Took my car to another dealer and complained about the wind noise and they immediately installed the SIB. The noise was greatly reduced, but not as quite as other F30's I've driven in.

I've subsequently complained about the wind noise every time I take it in for server, but it anyways comes back normal behavior, no trouble found.

I've just learned to live with it by turning the radio up.

I tried this a couple of months ago. Actually taped the entire window/frame joining areas on both front doors with no difference noted. My wind noise begins around 45-50 mph and increases from there.

Does anyone have the text for the SIB mentioned?

I took the Dealer Service manager for a drive during my last service appt. back in Sep. He agreed the noise is there and said that he has heard it in many of the F30s. He checked BMW's database and nothing was shown there addressing the issue

Real annoying.

I took a piece of paper and closed the door with paper placed at different points. What I noticed was when the paper was shut closed at the bottom of the front doors the paper would easily slide out compared to the upper portion of the doors. I have brought the car to the dealer 3 times telling them to check alignment and they keep saying it's fine. So I can finally show them proof of misalignment . Anyone else notice what I'm discovering here?

Yes!

I tried your paper test (what a great idea!) and noticed the same behavior. It's very tight at the top and sides, but very lose at the bottom.

I'm trying some ideas (currently using 3/8" backer rod stuffed into the of the door frame seal "U" area all along the bottom) and will report after I've had enough time to test it. Initial results are excellent, but I need to do more testing.

Background:

My wind noise is intermittent; sometimes it's very quiet, other times the wind noise is really loud. It's not road / tire noise, that's a different sound.

I've had the windshield trim fix and the outside windows trim gap fixed (as previously posted), but I still have what I would call intermittent, but significant wind noise.

I've always suspected that it's the door seals not making strong enough contact, but I have not been able to prove it. I don't think it's the door alignment (mine looks perfect), but possibly a misaligned / mis-installed seal installation on the door. I just couldn't figure out a way to verify it. The paper idea is brilliant!

A misaligned seal might explain the intermittent noise; sometimes the door seals just enough to prevent air from getting through, but sometimes not.

I have mentioned my misaligned seal theory this to my SA, but he said that the seals have pins on them so that they can't be misaligned. But, looking at RealOEM, I don't see the pins on the picture of the seals and there is a note saying that a set of templates must be ordered along with the seals; so if you need a template to install them, then I'd guess there aren't any pins!

If the backer rod fixes the issue, I will definitely report this to my SA and try to get him to have the door seals re-installed / replaced.

Same experience here too; when it happens, it starts at 50 mph and increases with speed. It's especially loud when there is a cross wind, or when turning left at speed.

I've tried taping the windows, the sunroof, etc. No change. So, at least for me, I think it's leaky door seals.

I've been on many test drives with the SA and the mechanic, they either say it's normal, or they don't hear anything. When I tell him I've been in several F30's that don't have any wind noise at all, he just shrugs. I've also asked him to look it up on their computer, but he says there is nothing about the issue there.

Will check today and report back. In fact I'll have a good look around the whole door. I'm honestly really surprised at how little wind noise there is...

[///Mangler]

I don't know how more simple to explain it then this. It is not the door seal. Wind is getting in up under the window sill on the outside. the edge of the window is not touching the back of the track so the wind goes around the back of the track and comes through the corner. If you watched the window when it is raining you will see a low-pressure zone all the way across the top of the window right back to where the gap in the seal is. There's a major low-pressure zone there in the noise you're hearing is the air being sucked out of the car up through the corner of the window. Here's a video of exactly what I'm talking about.

Put headphones on and listen to it see you can hear exactly what it sounds like in the side of your head while you're driving on the road. I drive 4000 miles a month and it's driving me crazy.

[snowghost]

I guess I'm "lucky" as my 2013 build wind noise is pretty nonexistent as Frogman can attest to.

At the back of your front windows does the glass to stay in contact with the molding all the way to the top or is there a gap? If you don't have this air sucking noise then your glass must stay in touch with the rubber molding all the way to the top.

What speed are you driving on this video? And how do you not crash when both hands are off the steering

It's not that big of a deal, once I finished my bowl of fruit loops and put down my skinny chai latte moving traffic got up to about 80 befor the next slow section so I threw in this little video meanwhile.

Yes the back of the front window is tight against the glass. If I run my fingernail along it, it's very uniform.

Exactly. That's why you don't have this issue. Look at every F30 you see from now on and half will have a gap and half will not.
