I've not been back to the dealer, it's not perfect, but have learnt to live with it.
The bush is the rubber or soft component between the metallic suspension component and the metallic sub-frame.

I had this issue on my 1 series with VSS and adaptive.
Replaced the steering rack - noise gone......until about 1000 miles later when it was back to square 1. BMW said it was normal although couldn't pin point the issue? have learnt to live with it since.....hope my new 335 doesn't do the same |

I'm sort in the same boat. i've had them replaced the swivel joint, steering rack and front left strut. noise is 70% gone but still there. very easy to replicate for me. just drive over a speed bump, if possible, one wheel at a time which will at least help narrow the problem area. my case, front left. i'm going back to the dealer to get them to fix once and for all. someone who is a BMW tech told me he had the same problem and advised that i keep bitching about it to them until it is resolved. customer feedback and satisfaction is huge for the dealer; if feedbacks are poor, they loose out on funding from BMW NA and bonus at end of year. so if you're not happy, let them know. also, the same tech told me i can always escalate with BMW NA if problem isnt resolved. no one should learn to live with any problems. |

according to a dutch forum, BMW finally recognised the issue with the adaptive suspension and recently released a software update for this. Drivers with the issue who had all rubbers/dampers/etc replaced and still having the issue, got it solved with this new firmware apparently.

I had this issue since day 1 and was told that it was a feature and not a problem. My car recently went in for its end of warranty checkup and they told me they had a software fix for the knocking suspension. I was very sceptical to say the least. Thankfully they were correct and now after 3 years of knocking over speed bumps, my car is perfectly quiet with not the slightest knocking sound. It is even quieter over rough mottled roads. I never thought that software could have solved the problem!!!

I sometimes feel I can force this noise to appear at the front by going over speed bumps. Going over the speed bump will cause a number of subsequent noises on the downslope and the first yard or so of flat that seem to bear no real relation to the road. The best I can describe it is that if it was coming from the rear, I would think there is something moving around in the boot. It is a bit inconsistent. It sometimes feels that, once provoked, it will be lurking for the rest of the journey. I've got Adaptive, May 13 build. Presumably, if a firmware update is fixing it, dealers are not going to spend hours troubleshooting if you report these sorts of intermittently reproducible noises?

My dealer has confirmed that there is now a software 'fix ' for M Sport adaptive suspension. Apparently they've installed it on a couple of M140s and it's worked.
Mine will be updated when it goes in for the bumper replacement.

Any chance you can find out from your dealer if there is a service bulletin out for this? My dealer can't find anything, trying to point him in the right direction. Thanks |

I've emailed my dealer - will let you know if anything further comes back, i.e. a PUMA reference or software serial number.

Hi All,
I am not sure if it's a full software update or just specific to the module which controls the suspension as I had to get a full update on mine due to bluetooth issues (And yes - I lost all my coding bits and pieces into the bargain and my nav got returned to 2013-1) When I asked about a fix for the knocking suspension at the end of warranty check, the dealer was quite adamant that this software fix would sort it. I got the impression that this was a well documented fix due to their optimism. My car is a F21 though (not F30) so not sure if the fix is model specific.

I had my car checked yesterday by my dealer (testdrive where he concluded that suspension didn't sound too good) and I have a follow-up appointment for next week friday where he indicated that there most probably will be new software programmed for the suspension. I asked if this was a full update for the car or just the 'suspension' module, but he couldn't tell me straight away as this could be depending on the current software level of the car. Will keep you updated.

F33 with adaptive suspension
Hi, just seen the long thread on adaptive suspension issues that seems to be rectified by software update.
I'm collecting my 66 plate F33 with adaptive suspension this Sunday, is there anyway of finding out if the software is already updated? |

as the (dutch) dealer do not update software by default, the car still might be on the factory software level. As this update is pretty new, likely it is not yet installed. But the dealer can check this via their diagnose tooling.
