Yes, just unplug it. Do yourself a favor and use some electrical tape to tape it down to something so 1. you can grab it easily later if you ever need it and 2. it's not rattling around in there.

Your other question I honestly have no idea, check the Dr. Stragelove thread or ask it there. Those guys know everything. I do not think you need to do anything when working with stock speakers. The only real issue that I know about that is fixed with ASD harness is there was a mistake there with the BMW wiring that the harness if you buy new now fixes, if you get an old one you need to swap two wires. Again Dr. Stragelove has all the info.

Good to know. I installed mine last night - a bit tough getting it into the space between the hinges and fender area, especially with my fat stubby fingers, but I think I have them properly and completely installed. Can't say I notice any sound difference but again I have a vert so I wasn't expecting any change.

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.

I am curious if the PN you listed are updated parts since they have a higher number? Or since one is a frame seal and the other a panel seal are they both meant to be installed together? I just would like to order the most effective part or parts and more expensive is not always better.

I just realized the first page of the thread lists two different part numbers:

From the OP:
EDIT:
I think the first page of this thread needs an update. Most people have agreed that the seals have decreased noise in the cabin. The seals are available for as low as $9.45 each.
Left side part- #51-48-7-348-779
Right side part- #51-48-7-348-780

and from Sportstick:
Part info is:

Driver side: 51-48-7-300-693 Price: $23.63
Passenger side: 51-48-7-300-694 Price: $22.96

I ordered and installed the parts referenced by Sportstick, but they look just like the pictures posted by the OP.

They are the same parts, just different prices.

If you say so. I read different part numbers and different prices.

My recollection of working this through with the parts manager is that there are two sets of parts, closely related in location. The price difference was similar to what we're seeing in this thread and the more expensive (although still relatively cheap!) parts were the ones which matched the OP's original photo. I wish I could recall the exact terminology used, but the parts under $10 each are not the same as the ones I bought, the taller vertical "stuffers" we've seen in the photos. If anyone has bought the low cost parts and can show that they are the same as the tall stuffers, please let us know...perhaps photograph the parts label with the number which came attached.

Perhaps I wasn't clear enough. I said that "they are the same parts" .

They do have different part "numbers" and different prices.

Many people have posted in this thread that they have ordered the cheaper priced part number, they fit exactly the same as the more expensive ones. My BMW parts guy looked up the part in his computer. He just happened to source a less expensive cross reference of the same part.

My car came from the factory with one strip on the passenger side. I installed the drivers side strip that the parts guy ordered for me, it looks exactly the same as the factory installed strip on the passenger side.

Plus, the 51-48-7-300-693/694 parts are the ones shone on the BMW exploded 228i parts diagram (part 5). But if the less expensive ones fit, I'm in.

Installed the weather stripping this weekend and I'm very happy with the improvement. Install took 10 minutes on the first side and 2 minutes on the second side. The car is like a library (with the sunroof shade closed) now. Well worth the $30.

[Tpeterson]

If anyone is still interested.... I stopped into the Motorwerks BMW parts dept. this morning to order the sound insulation parts and found the reason for the difference in part numbers. The 693/694 numbers are for the coupe as per the parts diagram and the 779/780 numbers are for the convertible. I don't know what the difference would be. Same doors.

[SlickShift]

I ordered the convertible part numbers and can confirm they fit fine.

Mine is a June 2016 production 218i Coupe and it has the strips.

Just had a look at MY16 M2 and no door seals! I only collected the car last Friday and it was the first long drive this weekend and I did notice when driving at high speed I needed to turn up the volume on the Music, then when slowing down I had to reduce the volume. I thought it was the bloody hum from the false sound thing but maybe I need these door parts.

I have just posted this question in the M2 section....http://f87.bimmerpost.com/forums/sho....php?t=1378394 lets see what other M2 owners say!

Are these parts visible at all from the outside, when the door is closed?

An M2 isn't going to have the seals because that's a car that you want to be a little noisy. Same with an M235i. Not so with a 2 Series 'vert.

No offense, but if you wanted a performance car with a quiet cabin, you should have bought a CTS-V.

No

220i coupe Oct 2016 production date delivered Feb 2017 has both seals on the 2 doors.

Since I picked the car new I could hear tyres and road noise more than the few beema's we had before, so if I would to have missed on those insulation strips, I'd be on them tomorrow like a cheap suit.

Current issue? - the rattles from the plastic covers over hooks on back seat and behind back glass - really cheap fit out that I'm taping off the rattles.

Oh the first world issues ! - love the car, esp after giving it heavy long drive and engine starting to come alive.

[Raptor01]

April '17 M240i Coupe, came without. Might look into them later on once I've had a bit of seat time.

[rightrudder]

Hmm, when I pick mine up I'll have to check for the presence of these seals. I'm sure it's a warranty "repair."

My April 2017 build M240i has the seals.

Hi,

Question to everyone who installed these strips:
- are the glued in (peel of strip)
- the phone on the first page shows them being added to the door but the pic on the second page shows them added to the door frame
What is correct or doesn't it make any difference

[selmeralto]

You just push them in. Takes a little fiddling. A 12" ruler will help.
