I have an annoying speaker based rattle from the HK centre dash speaker, it is not distortion whilst playing Megadeath, more a resonance on certain pitches, particularly Barbra Streisand and Lisa Stansfield. So Googled and removal of the centre speaker ensemble is easy, 4 x clips.

I know it is a warranty job but, BMW think the whole dash needs to come out. It appears to be impossible to explain that it doesn't, I really don't want my dash removing, as we know, there may well be 1 trillion rattles after that then I will go completely potty.
Does anyone have any experience of this issue, under warranty, what happened?

I have the same slight rattle under certain conditions and ambient temperatures.
I don't this it's regular enough to warrant BMW going at it and maybe causing more damage or problems, I've been tempted my self but then have never got around to it as I've had worse rattles in cars.
A bit peeved to have it on a BMW though.

I have the HK in my F31 do not have any rattle from the centre speaker. But I know from past cars when I've had rattles with speaker units they have come from the wires vibrating causing a rattling sound might be worth if you can pop the speaker out from the dash to look at the wiring and possibly add some automotive loom tape like this Tesa 15mm 25m Roll Adhesive Wiring Harness Loom Tape https://www.amazon.co.uk/dp/B00EVSD5..._fg4pCb4KBCJY9 around them or possibly to where the speaker sits to give a tighter fit by forming a type of tape gasket between the speaker and the dash to prevent rubbing or vibrating.

DON’T let them take the dashboard out.
I’ve only had that experience once, but the dashboard never fitted the way it did before.

Thank you, that is my concern, apparently after a 30 minute conversation today, they "have to what the warranty says"!

I can't live with it so a little DIY is in order, thanks all.

I don't have an issue with mine on two cars with HK. I would suggest a DIY. Some 3M foam tape. Or even some sound deadening acoustic tape/sheet. Don't let them take your dash out. I made that mistake with my E92 once there were scratches all over the driver side as they removed it carelessly from the car.

I have had my HK dash speaker replaced twice recently , due to a faulty amp , and it is a 5 min job.

Pop off the cover and remove four screws if both speakers need removed.

Could not agree more. The dashboard is unlikely to be same after removal. It happened to my previous 2013 BMW 335i. One rattle was fixed while multiple other rattles surfaces after dashboard reinstallation. Earlier F3x models generated more rattles. My 2017 BMW 440i GC has substantially fewer rattles at 18K miles.

I think I see your problem right there.

Thank you, oddly and rather scarily, I have the exact same clip on my phone and e-mailed it to their service department today.

Today I went to my friendly dealership and "explained" that they did not need to remove the dash and that I did not want them to remove the dash, my friendly service Manager spoke to someone behind a closed door, returned and agreed that they would not remove the dash (I will know). I then played a mix of Lisa Stansfield, Steely Dan and Peter Gabriel. I now have a rattily quarterlight tweeter. I have not played any Ariana Grande, do you think that would fix the problem?

Failing that it's booked in for Wednesday, so fingers crossed.

I will report back.

All done, centre speaker and door tweeter replaced.

Centre speaker still rattles, right tweeter is now fine, left tweeter now rattles sigh.

Car in twice, noise still there, went in today to play some music to their head technician. He agreed, they want the car for a WEEK!!!! apparently they will systematically test each speaker. I can tell them where the rattle/resonance is. I guess they want to get it right, my last visit cost them a set of wipers. Sadly due to the EGR recall, they can't fit me in with a courtesy car until mid March

[DannyT331]

Is it not mid March now?

That’s a decent wait!!

Ive got this on a few tracks, but usually it manifests itself at 50-75% volume on the knob. I have to get them to fix the squeaky brakes and rattly bootlid first, then will turn to the speakers as is less irritating than the other noises.

OK, after the eight visits to Dick Lovett Bristol I now have my car the way I wanted it 13 months ago,

Total work carried out:
Visit 1 - Centre speaker replaced
Visit 2 - All front speakers replaced
Visit 3 - "It is the HK system"
Visit 4 - All speakers replaced
Visit 5 - All speakers tightened and wiring checked
Visit 6 - All mids and tweeters replaced
Visit 7 - Major oil service completed - No donor car for a like for like test.
Visit 8 - Whole system replaced, along with all wiring, all impedances checked, same HU but every other part is new.

So, after 13 months I now have a system that sounds faultless. No rattles etc.

Thank you DL for never giving up and for putting up with my incessant whinging. I am still a little confused as to the weakest link but all now good - Shout out for Martyn and Steve Adolpho.

I have had my car nearly two years and the speakers recently seem to have come into their own and sound way way better than they did when they were new.

They say speakers are 'run in' after about 20 hours of use. I dont use my car alot lol.

So I'm sure your system will sound more than perfect in time
