Less parts better for their Inventory Management. That’s why they try to reuse as many parts as possible for different models.

As you are no doubt aware, Realoem does NOT show them as a valid part number on your 2012 front doors, only your rear doors.

Turns out this is exactly wrong. They worked on my front doors but definitely did not on the back. I have no idea what part number to order for the back.

For the luxury liner pro I used hook and loop tape on the door frame on the ridge below the window opening to mount/hold the luxury liner pro up. I essentially made the luxury liner pro pieces as large as the entire door card itself, and then cut holes in it for the door card mounts, wires, and speakers that needed to get through. I also made some relief cuts to allow the material to flex more where needed.

Thanks. I’m going to try this as the extra sound isolation pieces didn’t do a whole lot. What benefits if any are you getting from dynamite? Do you think doing the floor would help?

I tested it driving today and it’s mostly wind noise getting in between the door and car body on the rear top corner of the front doors.

As can be seen in the same post that you state is “exactly wrong”, Part 22 is grayed out on the 328 which means it’s not there on your car.

As previously stated, Just because it does not exist on your car doesn’t mean it doesn’t fit front AND rear on the OTHER BMW Model for the reasons posted.

Because it fits between the hood and the body. And the rear doors don’t have a hood.

Turns out this is wrong, they work perfectly and are completely “valid”.

I appreciate you trying to help. Just wanted to record for the next guy doing research that most of it was wrong. Not sure what to tell you.

Lots of luck in your quest.

I suggest any one learn how to read realoem prior to going down the path of assuming something is missing from your car or trying to fit a piece from a different model on your own car.

Here are 3 photos, with the realoem listing directly next to a photo of my car. I can't see anywhere that I'm wrong. But you tell me.

[rjjy]

OP HERE.

I drove around like an idiot today with tape and without tape trying to find this noise. It's coming from the topmost, rearmost corner of where the door meets the body frame. Almost like the wind is whipping over an air gap. It's also coming from the seat belt hole in the upholstery in the B pillar.

The tape didn't help. I haven no idea what to do next. Replace all the door seals? Just throw Second Skin Luxury Liner everywhere in the door and B pillar and hope it absorbs the sound?

EDIT: Should I try this 3M Silent Door Tape? (mute video, horrible music)

EDIT2: This guy applies the door seal tape in a different spot. Also calls is #4229 3M tape:

And this post has some nice detail about what I suspect is happening on mine too with the B pillar. http://x3.xbimmers.com/forums/showthread.php?t=1316217

I'm in deep now! ��

Again, good luck to you.

You still fail to see the failure in your logic and posts and I’m done with it.

That's why I asked again. I just spent 20 minutes making those 3 photos comparing them exactly to the realoem. I googled how to read realoem and didn't find anything. I'd love to know how I'm wrong. That's what I'm legit asking. I just want the sound to go away and I can't tell if you are trying not to admit fault or actually know that I screwed something up and aren't wiling to help. I can't see where I messed anything up. As shown in the photos I made it's pretty clear, I think, but that's why I'm asking.

BMW makes Parts to fit multiple cars and areas.

For example, the door pull trim in a F30 fits the front and rear so BMW has fewer parts.

That does not mean that the front door pull trim from a F30 fits the front door pull trim from a F32.

You are attempting to take a piece from a different model (where the front and rear are the same) and install that on your different model car where it is grayed out as it’s not applicable and expecting it to fit. You claim it won’t fit because it’s the rear part and that realoem screwed up because it’s the same part number in the other model it was made for.

It’s not fitting as it was never meant to fit your car and you are assuming it will.

Peace out.

OP HERE. I'm going to try this. And extend the Z type across whole B pillar.

I am not. Same exact model. See extensive photo documentation. I even provided last 7 of my VIN so you can verify.

Are you really this dense in real life?

This is my last response to you as you are going on ignore.

Lots of luck trying to figure out why M3 Parts dont fit on a 328i....or a front door seal where there was never meant to be one on your 328i.

LOLOLOLOL You just proved my entire point you idiot.

328i schematic shows part #22. BUT THE PART NUMBER IS NOT IN THE TABLE. So I smartly looked around for other schematics with the exact same part, and linked it on the M3. Which shows the same part, but labeled #2 now, and the part number is #51487301069. So I ordered that and installed it perfectly in my 328i.

Again you are exactly WRONG.

Just to recap
1) the part numbers are exactly the same
2) my realoem screenshot shows it on my 328i
3) and wait for it, the ringer!.....THE REAL LIFE PHOTO OF IT INSTALLED ON MY FRONT DOOR

Get lost. You're confusing future people reading this thread.

[SecretAsianMan]

I almost hate to revise this thread, but OP I could use some help. I ordered the front door seal parts that you've clearly installed successfully, and I cannot figure out how to get them in. I can snake them into the hinge area behind the actual hinges and electronics, but the space is SO tight I cannot push the seals in.

Do you have a guide on how to actually do it?

My 2013 428 had the foam seals between the wing and chassis in front of the door as in the diagram. My 2015 428 car doesn't have these foam inserts.
They don't make any difference in terms of noise. It doesn't seal the door, it just fills the gap between the wing and chassis. The door has it's own seal.

The wind noise comes the door mirrors and the F3x has a thinner windscreen. I think the window glass is also thinner.

A lot of the noise also comes from the runflats depending on the road surface.

[sygazelle]

The #1 way I've found to keep the cabin quiet is to put duct tape over the mouths of sceaming passengers. Works like a dream.

[track.n.trail]

If you're still on the factory runflats switching those out is going to make the biggest difference in road noise.

[blankito]

I agree tires make a HUGE difference.

Just switched from my winter tires (nokian hakkapeliitta) to summer tires (Michelin pilot) and there is a lot more noise in the cabin, especially on the highway

Even though I removed the roof rack, the summer tires generate more noise than the roof rack.

[Wires]

Just had my windshield swapped for an non-OEM, and the glass shop put in a an "acoustic windshield". That really reduces the wind noise from the front of the car (still wind noise from the side glass though). Makes me want to swap the side windows for their acoustic equivalents….
