They "confirmed" the issue and they replaced both window guides:

51 33 7 258 325
51 33 7 258 326

Inspecting the installation shows that at the top end of the door where the seal slides over the is very much tighter than my previous seals were.

Initial results were very positive, but it's hard to say how much difference there is on short trips in traffic. But the difference was easily noticed by both of us. It's hard to tell sometimes as I think I'm mistaking wind noise with road noise.

We just got back from a long trip (LA-SFO) and I'm very pleased with the reduction in noise over about 10 hours of fast I-5 driving under lots of different road conditions. I think I'm finally past this long-term wind noise nuisance!

Notes:

1. Over a really good road surface (there actually is some on I-5 theses days), the car is virtually silent; It's never been this quiet before. I very pleased with this.

2. Over bad/patched/grooved sections (still lots of those on I-5), the increase in road noise is huge and probably amplified by the run-flats. I think a component of the road noise manifests itself as wind noise, but isn't. It may be just the sound bouncing off the windows.

So, if you can show your SA that you have a gap between the glass and the seal at the back of the windows and/or report that it sounds like the window glass is not sealing properly, maybe having the window guides replaced will fix the issue for you. It did for me.

I sold my car so there was no resolution on mine.

It's a very easy thing to demonstrate. Get some painters tape and tape the top 6 inches of the driver and passenger windows backtop corners. Go for a drive it'll be silent. Videotape it. Remove the tape and go for a drive you'll hear the wind vacuum noise. Videotape it.

Possible this fix for a honda accord could work for us!

Just thought I'd share...

Like everyone else, I had wind noise since taking delivery. Having read everyone's experiences here I think there are multiple issues that could cause this and different interpretations of what "excessive" wind noise is. Mine was pretty bad and it seemed mainly (or even "only") on the drivers side. Hell I'd hear wind noise sitting parked in the car on a windy day and of course any time I'd go over 50mph. People on the phone would say "do you have your window open?!"
I lived with it for a year, thinking it was just part of owning an F30. But while detailing my car a couple weeks ago, I noticed that the rubber seal along the top of the door (not the window) did not press snugly against the door frame for a good 10" length. In fact, there was a fairly significant gap of about 1/4 - 3/8" at one point!! All other doors had a snug fit.
I have no idea how I missed this before and I think the gap may have varied depending on temps. But this would clearly cause the excessive noise I was hearing since it would be wind rushing over what is basically a hole.
I took the car in for my first service and they reseated the rubber and adjusted the door latch to pull the door tighter closed.

MY excessive wind noise is gone!

Is it now completely silent? Well I have sensitive hearing so no, it's not silent. But with the seal fixed, I can now pickup the more subtle wind noise from around the car. But it's about 90% improved and honestly not more than any other car that I've driven in this class.

So if you haven't checked, look at the seal around the top of the door and make sure it's tight.

Sideview Mirror Design Differences

As I've driven several loaner F30s, the wind noise seems to be less with those loaners compared to mine. Granted those cars didn't have shadowline trim, but it appears that they've changed the design slightly with one slightly larger ridge rather than two ridges.

Picture of my 2013 F30 with two ridges



Can someone with a 2014 or 2015 confirm they've changed the side mirror design with one ridge? This is the closest I've found...



Because if there is this change, I may bring it up at my next service since it would probably improve the wind noise quite a bit.
