The direction from where the sound comes from can be very deceiving I've found. You've obviously tried just about everything and I really can't offer any further ideas, except I wonder if it's something to do with the exhaust.

Just thought I'd throw that one in, as mine ticks sometimes; although admittedly usually once the engine is switched off.

Sorry I can't offer more help, but hope you sort it, as these sorts of things can be the ruination of driving enjoyment can't they?

I didn't consider the exhaust, but that's a great idea. I will see if there's anything loose down there. I also get what you mean about the direction of the noise. I've had a couple of people sat in the rear and asked them to point it out, but they couldn't really pin point it.

It shouldn't bother me a much as it does, but I just find it super irritating.

 

Have you checked inside the cavities where the rear lights sit?? There could be something loose in there, alternatively I'm sure there'll be some wiring looms that could have been poorly routed & are knocking against something??

 

I completely understand what you are saying here Mooeeey.

I have the exact same problem and can not for the life of me find out what it is. Again same as you some times its there and sometimes its not. I want to say it sounds like metal on metal but its not really that sort of metallic sound that you get, it does sound like maybe plastic on metallic or vice versa...?

I did read a post on here about the seals being to tight or loose and maybe that could be the source of this rattle. I was going to try some sort of lubricant to see if that helps. But will be watching this post carefully to see if you have found the solution to the problem.

I hope that its not the exhaust only had the car 1 month so would not expect a brand new car to have a fault like this already.

I know this post does not really contribute to helping solve the problem, but just letting you know that your not the only one.. haha were in this together.

 

oh and it is coming from drivers side boot area for sure.....

 

seen this and might do the trick. can only tru for less than £4.50...???

Does it go away if you put something heavy in the boot/rear seat passenger? I had a damper go on my e91 and had similar sounds to start with (got a lot more obvious when it really went). To start with it went away with anything heavy (~>50kg) in the boot.

Glad to know someone else feels my pain I won't give up, if I find the issue I will let you know.

When I took the boot lid trim off I did indeed check the light cavities and all wiring connected to the boot lid, although I didn't think of checking the other lights, which I will do tonight.

Someone at work mentioned about the windscreen washer pipe could be me making the noise, but I have no idea where to start to get at it.

Thank you. I have a spare wheel in my boot at the moment and my winter kit, probably doesn't amount to 50kg though. I'll add a little more and test it again.

 

I drove myself mad with something similar which sounded like the rear seats creaking and rattling until I cleaned the sill around the sunroof. If you have a sunroof give it a try as I was convinced the sound was coming from the rear until I did that.

 

Mooeeey. From what I´ve read so far, you have one positive lead. "The tight right-hander". Have someone with you in the back seat to help with listening. Go back to that tight right hander or similar and try to replicate the abnormal noise. (Have your car in the same condition as at the time when the noise was detected). If unssuccesfull, then let the passenger out and try it again. If you can successfully replicate the noise few times, then se your BMW dealer, demonstrate the noise and let them to take it from there. If you can´t replicate the noise, then try to drive with someone in the back seat as often as possible to help you with your task. It is very difficult to pinpoint this type of thing on your own. I have some professional experience with tracing abnormal noise in cars.

Thank you! just been out for a drive and I'm 99% sure the noise is coming from this area...

Had someone sat in the back and we took turns driving and both agree. Peeled back the trim a little and I can see a few wire looms, but wasn't sure how to remove the trim completely, so going to try at the weekend. If not then I will get it booked in with the dealer Making progress slowly!

 

Just goes to show how we almost constantly discover new things about our cars. Having now seen your pic of where you believe the noise is coming from, I noticed the speaker and housing and initially thought 'I don't recall mine being like that!' I've literally just stepped out of the house and had a look and voila ..... exactly the same ..... doh!

It was the same with the M135i, which had a couple of raised plastic strips adjacent to the wing mirrors (believed to be something to do with helping noise reduction I think). Many of us had never even spotted them, despite washing our cars countless times!

Being one who doesn't 'frequently' wash his car, I shall await grief from Octavius now for having made the aforementioned comment!

 

It still ticks and rattles with the boot lid trim removed completely?

OK. Glad, I could be of some help. Be very careful removing the trim. Don´t try too hard. You know.....if you damage it, you pay for it. Best of luck!

Yes it did. I checked all the cavities too. Nothing loose, nothing knocking against anything.

 

Mooeeey, just an idea. If you can lift the trim far enough to pack in there some soft sponge ruber (foam) to secure the wiring, it often does the trick. Anyway, I think it´s worth trying.......and saves you from ripping the trim completely off.

I've taken the plastic bit of trim off tonight. Lots of wires, but none of them the pulpit. Going to remove the rear speaker and surrounding trim tomorrow.

 

Mooeeey, the visual check is the one thing and the dynamic check is an another. Therefore, try to drive your usual tight right hander with the trim off and see, if you can generate the noise. If the noise is stil there, you have eliminated one variable. Then proceed with the removal of speaker and the trim. Repeat the procedure. Visul and dynamic. Good luck!

Had a go this afternoon with the trim off, and all the other bits too (parcel shelf, bootlid trim, etc) the noise is still there had another friend sit in the back and listen who thinks it's suspension related.

Anyway I've semi given up and booked it in with the dealer. I also somehow managed to damage the taillight (small bit on the boot lid part only). A small bit of plastic has broken off (holding the light neatly inline with the body), so the light doesn't sit flush with the body. So best case it might be this I need 63217435200 (small cover thing) or worst case the whole light 63217359019. My own fault totally.

Here's a video of the noise. Added a crude visual indicator (red dot) to identify when the noise I am talking about happens.

Hopefully the dealer will be able to locate the noise.

Thanks everyone for your input so far. Very much appreciated.

 

Hi, after seeing your VC and listening to the random ticking noise, I went to check my car to familiarize myself with the set up.
Area, RR suspension inner garnish, is a drum like feature, ideal to transfer and resonate any abnormal noise coming from anywhere in the quarter panel/wheel housing/suspension turret area. The noise could even be related to a faulty spot weld.
I think, you´ve done the right thing to let the dealer to take it from there. Please, don´t forget to let me/us know, how you went. Good luck!

I have the car booked in mid May when I have a break in my schedule. So I will let you know how I get on shortly after hopefully

 

OK......and good luck!
