It should make the same change on the convertible as on the coupe. However, with the other sources of noise in a convertible, you may or may not hear it, but that path will be blocked, allowing you to chase down other sources for possible correction. The one convertible loaner I drove was noisy from seemingly several sources, though, so this might be a bit of a task.

After living with the vert for year, I'm guessing that the largest source of noise by far is the lack of sound insulation in the convertible top, and doing this is not going to cause any noticeable reduction in the overall noise level. But if I'm wrong, I'm interested. The overall noise level with the top up is probably the most significant complaint I have with the car, especially given that I know the noise level could have been significantly lower with a better insulated top. |

M240i door seals
Just replaced my '09 335i xDrive sedan with a new '17 M240i xDrive coupe (including H/K audio), and both doors on the M240i have the seals.
I have to admit, the road noise in the cabin is much higher in this car than I thought it would be. With new non-runflat tires I thought it would be quieter than my old car, but it's definitely louder to my ears. Time to deaden the undampened panels in the back and doors, along with putting a better crossover network on the components in the doors. This, combined with an LOC/Amp for the subwoofers, and I think the sound will be greatly improved. |

My 2017 240 convertible came with the door insulation. I don't notice excessive noise in the cabin, but I don't drive much on the highway or at higher speeds around town. Also, I drove an E46 M3 convertible for some years prior, so I may also be used to the compromise. I'm on 18-inch non-runflat tires and it's been mostly above 50 here in Atlanta.

Installed this weekend on a 15 M235. For the past month, I have had a commute on a whining (tire noise) road and through a tunnel. For the first time in over 30 days, I was able to listen to my audible (Freakanomics) channel at four clicks (vol button on steering wheel) lower than previous 30 days. I usually have to crank it up in the tunnel due to echoing engines, etc, but today was much more mild than I have heard previously.
I also ride on Michelin A/S3 tires, if that means anything - but I have not changed these in over a year, so my ears are already attuned to them.

Hey everybody... my second post here... I have been lurking on this forum for a long time..
Took my car in for some warranty work (Bmw od Arlington - Texas) and asked about the weather strips... mine were missing and they said all models come with it besides the M235. Bought them for 22 dollars each and they threw free installation. My initial impression is about 30% less noise... esp highway speeds... worth the money for me. |

I have purchased the weather strips and plan to install them (unfortunately, they were a bit more expensive at my dealership), not so much as a noise reducer since I have a vert, but hopefully to reduce dirty water and grim slipping between the fender and chassis into the door area. We'll see it this accomplishes my goal.

It is really hit or miss. Reading through the entire thread, some 2 series come with the seals and some don't. There doesn't seem to have been a definite pattern in the past. I am the OP and mine came with only one which was on the passenger side. I do think it is worth the trouble if you want a quiet cabin on the freeway.
I have seen a few different part numbers listed in this thread, some have different prices. The ones that I bought which is listed on the very first post of this thread were the cheaper of the part numbers at the time, they all do the same thing. Last edited by AlpsRider; 03-23-2017 at 10:21 AM.. |

I put the driver's side strip in a few days ago (the passenger side is on backorder, apparently ... should be en route soon). It makes a significant difference, particularly with tire noise -- and for those with audio upgrades like me, the strips make a better-sounding audio system even more worthwhile to have.
