Hi, I've gotten some annoying noise when turning the steering wheel, clearly coming from the interior, and it sounds like it's from the actual steering wheel.

Mercedes changed the steering column module first, which actually only made it worse, and have recently changed a ring within the steering module, which only did minor help with the issue.

Now what is really weird, is that if I pull out ever so slightly in the airbag/horn, the sound gets much lower, so clearly something is stuck or grinding within within the steering wheel itself.


Does anyone else have this issue? heck if I slide in a credit card (stupid I know), between the airbag and the steering wheel frame, it gets alot better aswell.

Now I've been to two differerent shops, that sorta threw in the towel in a "new model new issues, wait for a recall" sorta attitude. Altho I've seen others in FB groups have the same issue, and got it fixed, one a plastic plate brushung aganst the steering column slip ring... whatever that it.

Any advice on how to fix it would be much appreciated, nothing worse than turning the wheel and that high plastic grinding noise.

added video for the sound

 

There is a tsb issued by Mercedes in March 2023 for the steering wheel noises.
Even though it doesn't mention "W206" in it, apparently the list includes new C Class models too.

hi

any solution for this?

 

not any I know, seen others have stuff changed which fixed it, but not seen anything ob what’s really causing the issue.

 

I currently have a brand new W206 with 1100 km on it, and apparently, I am experiencing the exact same issue.
It occurs only when I turn the steering wheel to the left, and after 20 degrees.
Also, I've noticed that the noise doesn't occur when the car is cold-started; the creaking starts only after it has heated up.
The noise occurs both when the car is moving and when it is stationary

 

hi, I found the error and sorta fixed it myself, untill mb figures it out.

First excuse my english, it’s not my first language.

the large black center of the wheel with the logo on it, is one piece, behind it at the lower part there are two spring on each side, I suspect these for causing the issue. If you pull out not too hard at the bottom of it, and turn the wheel while doing so, the sound should be gone or change.

I’ve had it at a workshop three times, and the mechanics had no fix, they dont do improvised fixes.

I bought some slim soft plastic pieces and slided them in, between the black piece with the logo and the wheel, possible if you pull it out slightly.


idelly i’s remove the center piece and fix it better, but I’ve got no ide on how to disable airbags, and rather not risc an incident.

anyways, the sound is gone, the horn works but I just press on the upper part of it.

in this video, around 20-22 second, you can see the two spring in the side of the airbag, which is suspect are making the noise

 

Thanks Shazknee, I managed to rectify this issue after reading your message.
I removed the battery, removed the airbag and greased every contact point, including the springs. The noise is gone. The entire operation was very easy.

 

 

Hi,

I have the same issue.

How did you remove the airbag ?

Thanks !

 

You have to poke the two holes on either side of the steering wheel. You can feel them by finger. Insert screwdriver into the holes and the locking mechanism should release the airbags.

 

I Mhave a 2025 c300 amg line in USA with 2300miles. same issue i even sent my tech a video simillar to yours. they replaced the steering collum module and it has only got worse. put it back in the shop yesterday. please give me any update or email me if your issue got fixed.

 

still have the car? i have the same issue with only 2300 miles

 

The fix is easy, I already explained it. You have to remove the airbag and grease the contact points, especially the springs. It was a permanent fix in my case (over a year ago and no noise). Steering column had nothing to do with it.
