Wanted to follow up on this : My car is fixed. I took it to the BMW dealer to try and have the noise issue resolved, cost be damned. I was fully expecting them to tell me to pound sand. They immediately identified the issue, told me there is a PUMA case on this and changed out a few parts. I have asked the service advisor to give me the PUMA reference number or the list of parts that were changed, he said he would try but since warranty work is invoiced by the dealer to BMW, there are no guarantees.
I will update this thread if I can find the information.
To anyone having noise issues, don't despair !

Hi, during the inspection you will not find anything, they sent me a couple of new shock absorbers and they make exactly the same sound as the old ones
I mean no offense but what is the probability of you receiving 2 batches of bad shock absorbers ? I think that if anything this proves that the noise comes from somewhere else. Have you tried reinstalling the stock shock absorbers and has this fixed the noise ?

Yes, I put the stock dampers and the noise completely goes away.

Sorry about your bad luck. Do the shocks make noise in every stiffness setting ? Have you tried calling the Ohlins HQ in Stockholm or their German offices ? I have found them to be very pleasant and willing to help, they should make things right for you. Two sets of bad shocks is not acceptable, it maybe a fault in the manufacturing process. My shocks definitely are quiet. Good luck ! I hope you can get this resolved.

Thanks, I tried everything that was possible, of course I called Germany and sent them my shock absorbers, they said that they didn’t find anything that caused noise, and they sent me a couple of new shock absorbers. But over time they also started to make the same sound

I do not know how to explain it, but it doesn’t seem like a noise of a shock absorber,but very similar to the clicking on steering wheel. And it is very audible when the car is standing on a slope and is driving slowly.

No disrespect to anyone however knocking, clunking, clicking and poping are all different noises and are subjective to person posting. Using one term over another will get different responses. For instance knocking people will gravitate to something loose or top hats, poping for end links and clicking something internal to the shock as an example.

So all I'm saying is try to be prescriptive and be open to issue lying outside of the shock however being induced by the shock.

I for one understand how frustrating it can be when you don't know what the actual noise is and chasing your tail forever wondering if it is normal or not.

I agree. It's very hard to know if others have the same sound and same issue as me without hearing their car or driving it. I should upload a video of what mine sounds like so others know better if they should listen to and follow my solution, if I ever find one.

However, I don't think the general discussion is useless, because it gives others (and myself) ideas of what to try to fix or replace. I think the best course of action for anyone is to gather a list of possible solutions, list them in order from cheaper/easiest to most expensive, and run down the list until the noise stops. Right now, myself, and maybe others are a bit like chickens with their heads cut off until there are enough opinions and thoughts to make a list like I mentioned.

I'm giving my car to my mechanic to install a DP in the next week or so. While there, I'm having him replace the top hat bolts, the carrier nut and bolts, the stiffening plate bolts, and check torque on the front axle supports. If one of these fixes the issue, I'm not gonna know which it was or take the time to find out, because they are all simple to replace. But if it does fix my issue, it will give others an idea of what to try.

Top Hat Nut x2 - 34339806226 $3.52/ea
Shock Carrier Bolt x2 - 07119905418 $4.79/ea 56Nm
Shock Carrier Nut x2 - 33326768884 $1.79/ea 56Nm
Stiffening Plate Bolts x8 - 33326768354 $3.31/ea 56Nm + 90 Degree rotation

Actually, I just looked through my order and forgot to buy the top hat bolts. So I won't have him replace them this time because I don't want to pay for shipping or wait for them to arrive.

BTW, here's a pdf I was sent with diagnosis repair procedure for Front Axle Steering Noise Elimination. Other than the carrier bolts and stiffening plate bolts, it also recommends to check front axle support bolts are torqued to 19Nm. Then goes to Lubricating the wheel bearing if those three fail to resolve the issue.

Update on my situation:

Vorshlag did not find anything wrong with the camber plate and noted that a dealer used alternative camber plates, dinan, GC, and vorshlag with the same noise. They believe it is something that seems to be dampened by the stock top hat but not any of the other camber kits.

Here is a video of the noise when the shock is compressing. The louder noises are from the jack going up and down from the center point, but the softer noise is coming from the shock assembly area.


I am stumped as stock top hats are virtually noise-free but with the camber kit installed more than once to confirm proper fitment, it makes this noise.

Yes, my noise is different than yours. Will get a video up later today.

My appointment at my mechanic isn't until Aug 5th, but after reading more. I'm starting to have little hope what I posted above will solve the issue. Will update after though.

It is a valving noise you are hearing?

Well, replaced the stiffening plate bolts, strut carrier bolts, and tightened the axle supports and still have the same sound. We actually tightened the carrier bolts 1/4 turn past torque spec and the creaking got a little quieter. So my mechanic seems to think the tolerance on my KW V3's is a little off. Which, I bought them NIB off of the classified section here, so I got no warranty.

Just chiming in that my Ohlins are noooisy. I have two separate things - "clunking" when at slow speeds /wheel turned / going up an incline/decline. Second is ticking noises when going over bumps. I was told that the ticking noises are because the cup that the suspension sits in is steel whereas the ohlins are aluminum so it makes a noise and you have to grease it every once in awhile. Haven't greased it yet.

OEM shocks are aluminum too.

I installed Ohlins a few months ago and have the same problem and it sounds like the noise in this video. In the video, you can clearly see the spring rotating causing the noise. If that's my issue, would that be the upper strut bearing? I don't have camber plates.

Sounds like mine but loud enough to hear in the car.

Interesting thread. I have MPS. I have what sounds like a loose back box hitting the subframe or chassis when coming off speed humps and/or corrugated sections of road. BMW are investigating whether this is the rear shocks, the rear top mounts, or something else as - apparently - it isn't the the exhaust. Even though it stops doing it after the first few miles...

Update: New rear dampers required.

I had Ohlins installed 2 weeks ago on my M2C. I got notified by my installer that the dealer will now be rushing some parts to repair the front shocks because 5 sets were recently installed onto M2/M2C by my installer, and 4/5 (other than me) reports that they make noise in slow speeds and parking speed. The installer noted that the noise is more noticeable if you have DCT, and my car is 6MT.

Apparently Ohlins had updated from the bottom metal bushing to the top copper colored bushing and that's the cause of this low speed noise. So now the 5 sets will be rebuilt, using the old style bushing.

ashtaron14 thanks for the info. What type of noise was it making at slow speeds?

Also I don't see how transmission choice affects the noise besides a bit of added weight.
