Rattling, Buzzing, etc... Anyone else?

I had this issue with my girlfriends' 2000 323...I took the brakes apart, sprayed the back of the pads with Brake Pad Quiet (yea, I know) and reassembled. This stuff dries like glue and makes the pad stick to the caliper....problem solved

Yes, it's only in reverse!

Bmw checked it 3 times. They even shaved down the pads. I know at least 4 other M4 owners who get squeaking in reverse. After they shaved it down and removed brake dust it's still there but not as bad.

I'm going to ask them to replace all the pads soon.

Maybe its the infamous issue of tiny stones getting caught in the shield? Solution everyone seems to suggest is to bend it open a bit more as to allow the stones to fall off, rather than being stuck and grind, thus making the noise.
Also why do you drive in sport plus all the time? Keep in mind stiff springs + not very good road conditions = rattles.

I was getting a really harsh rattle when I decelerated and the transmission (DCT) was downshifting. After multiple visits they finally localized it to the rear view mirror assembly and replacing that fixed the problem.

Now I am getting a nearly constant high pitched loud rattle which I localized to the center armrest door. I can feel it under my arm and it's louder and directly in my ear when the door is lifted up. Need to get that replaced soon as it happens on nearly any slightly rough pavement.

Also I have the convertible and it always sounds like the roof panels are rubbing against each other and the rear deck. They said they all sound like that and there's nothing they can do. I've had a 335 and an E93 with the same roof and it never sounded like that. Maddening!

More "driving" less "listening" with a notebook out may help the issue.
Go to a track, mash the skinny pedal, then you will understand why this car cost a lot and guaranteed that when you're at an apex with the tires on the limit of loosing traction, you will not have any clue of brake squeal, creeks and rattles.

It's a sports car for "driving".....aggressively. If you want quiet, I'm sorry but I recommend a nice non sport anything 3/5 series or Lexus GS with all the bells and whistle. It will cost much less than an ///M and you will have serene silence, but the skinny pedal will be mushy and lifeless.

You can have a porn star at home that gives you amazing dirty nasty sex all night long, looks vicious in anything she wears, have a vague idea what a kitchen is and comes with all her crazy shit and high maintenance fees or a Martha Stewart that'll cook a vicious meatloaf, will have no clue what a thong is, keep the house immaculate, balance your check book and will occasionally once a month maybe have "sexual intercourse/love"...with the lights completely off and only at night.....
You can very rarely in extreme cases find both, so pick one....

Is this supposed to be a serious question? I would take my smokin' hot pornstar to the cheese cake factory, order the meatloaf and have her give me a sloppy blowjob under the table as i eat it!

Exactly, so you got the M3 then.

I want both and, to be honest, it should be expected. Just because the M is an awesome performance car doesn't preclude it from being well put together to avoid squeaks and rattles. They aren't mutually exclusive and other manufacturers get it a bit better. We aren't talking about engine and exhaust noise... That's supposed to be loud! We are talking trim fitment squeaks, etc.

Cake and eat it too... I kind of expect that

Like who....that makes a car that you can actually track hard without compromises yet drive in daily life relatively normally. Every single competitor cannot match the M3/4s track worthy capability. All will get remarks such as massive body roll, understeer, etc....you can have "fun" at a track with an RS5 but it won't be competitive lap after lap.

In any case, I don't think you'll find a car that does both at this level. The M3 tries but not 100%, however it is still competitive with Corvettes and Porsches and it has four doors and just like my STI and Evo who had rough suspensions and rattly interiors, I bought this car for the driving and performance not the silence and serenity of transport.

Do you really honestly believe that you're going to be able to lap this car at triple digit speeds and thrash it around a track then drive home in silence...come ooooonn. Which begs the question, how many of the "not happy" crowd are tracking their cars, and if not, why not, did you buy it for performance or luxury.
BMW specifically makes this car with performance first then luxury as an afterthought.
I'm just playing devils advocate, I in fact don't track mine(yet), and it has creeks too, which I plan to have checked out but I ultimately understand the point of this car. I don't get caught up in "BMW $$$luxury$$", I get caught up in BMW "M 0-60, no understeer, track", and there in lies my pleasure in ownership.

I haven't tracked my car yet and it's rattling everywhere on top of the brakes squeaking every time I go in reverse.

I also wouldn't compare our cars to an Evo or Sti. I would expect those two cars to rattle like this, but a car I spent $85,000 on shouldn't rattle from me using sport plus mode, especially after 3500 miles. The car is still new!

I spent $140k on my GT3. I've only had it 6 weeks so it's not been to the track yet. The brakes squeak not only in reverse but also forwards (how often are you in reverse) and it rattles from about 3 different places inside. My last Porsche, a 997.2 GT3 RS, did the exact same thing. I still love the car as I do my E92 M3 which has more rattles than the last two pickup trucks I've owned and used hard. European performance cars rattle and squeak, whether they have two doors or four, and whether they cost 70 grand or 140. Just trying to provide some perspective.

First of all, the price of the car has nothing to do with rattles and squeaks. You can watch Chris Harris McLaren P1 video, and when he's driving in the city the thing rattles like crazy. It's easily audible from the video. And that car is $1.2M. Ferraris rattle. Maseratis rattle even more. Jaguars do. I think Audis tend to rattle less, but an Audi RS5 is heavier than M4 convertible, and that weight is mostly on the nose, so I don't think it's a good compromise to be in a non rattling car.

Secondly, well, mine rattled a little bit when I got it in February, but once we got above 40F here in Boston, it stopped making any noise.

I wouldn't exactly call your car factory fresh new.

People get awfully worked up when this gets discussed like it is an insult to BMW and a blasting of the M line Let's be clear... I absolutely love the car. I love all things M and BMW. I will buy another one in a year or two. I understand the inherent compromises with performance cars. I track my car in a meaningful way... BUT... I still think BMW could do better in this area. For example, there is no reason the CF trim on the dash needs to pop and crack over every bump. Some well positioned felt would fix it but they didn't bother. Their bad. Fixing little things like that (and don't forget, this is a regular 3 series "luxury" car interior ) doesn't impact or take away from the serious focus of the car. It's just attention to detail.

P.S. My C7 Stingray was a better track car and had no interior rattles or squeaks. I'm not suggesting some don't but I do believe Chev tried their best to fix that in this generation of car because people saw it as a flaw. BMW just needs to pay a bit more attention IMO... regardless as to how great the car otherwise is.

Ummm we have a Lups in our forums who has made us all believe that this mythical unicorn you speak of does exist.

Will save this post and read it to my boyscout troop at our next campfire meeting.

I'm not very good at cleaning and I consider laundry men's work. Like my car, I have my weaknesses.

[yaymitch]

I have had six BMW's and the only one that had issues with rattles was the 2002 M3 that I had. I have since had a 2009 C63 and now have a 2013 CTS-V with no such issues. I love BMW but they should have better quality control for the amount of money we pay to own them. I put up with it in the M3 but understand why some don't. Good luck getting the issues resolved. I just ordered a 2015 M3 so hoping I am lucky and don't have too many rattles and squeaks.

Ordered: 2015 M3 MG/SO 6MT

Don't bring your voice of reason in here! I do enjoy a good day of laundry though.

+1 mine buzzes as well....but that's really the only buzzing I hear...this has been the most squeak free BMW I've ever owned...the only other issue I have are the windows creaking which has been an issue in every single BMW that I've owned.

My plan is to bring a list with me to my next service.

ive been experiencing this grinding sound coming from the rear as well!!

did you get this fixed??

would appreciate some insight, its driving me crazy

I had an annoying dash rattle that was intermittent, but I finally tracked it - it's from the top of the steering column. Just have to find a way to stop it now but I know if I press on it with my hand it stops the rattle.

[blschaefer1]

Is it possible they addressed the source of many of these rattles, etc. in the '16 models?

My M4 is a '16, and thus far it is solid as a rock - nary a rattle or odd sound. It's one of the things I am very impressed with regarding the car.

On the other hand, both Porsche's I have owned were absolute rattle traps. My 981 Cayman S was a disaster. The rattles and creaks emanating from the rear hatch were non stop despite several attempts at the dealer to fix them.

One thing I noticed on the P cars - tire selection can have a huge impact on resonance in the cabin and therefore rattles. In my 991 C2S, I switched from OEM Pirelli P Zeros to Michelin Pilot Super Sports and rattles were reduced by about 50%.
