The little knob adjuster on my 2014 GLK350 4Matic will still move the steering wheel backwards and forwards but not up and down. Makes a little noise but nothing. Just started a week or so ago. Any thoughts as to why?

You either have a faulty switch or motor-----start testing

dvintglk

How do I test for either and is the switch or motor a DIY option?

What is that plastic/rubber coupling that appears to break often that controls the up/down steering wheel tilt function for a 2014 GLK350 4Matic?

Plutoe

You either find someone with MB DAS to test the system or you find a wiring diagram, buy volt meter, spend a week dismantling the steering column access the motor and start testing.

Or you can give the steering wheel a good WHACK! from above, which should release the blocked motor...

Well giving the steering wheel a whack did work in this case and the up/down tilt is working again. I heard there is a way to disable where the wheel auto tilts up when the car is turned off and down into place when turned on automatically. How do you disable that feature?

andreigbs

Nice.

That is one of the "convenience features" that you can disable in the menu, using the steering wheel buttons. I believe it's called "Easy Access" or Easy Entry/Exit, something along those lines.

I had the same issue on my 2011 x204....just wack the steering wheel in the direction you are tilting....and it should jar the motor loose.

My W204 is going to the dealer tomorrow for this (warranty). I believe I will be activating the exit option once it is fixed to save the motor.

Took the car in this past weekend. I explained to the service writer my issue and he told me to have a seat. As I am watching, the service writer played with the telescoping feature and came back to tell me the car was fixed. He said all you need to do is operate the working feature to loosen the motor. I then told him this appears to be a common problem. He told me it wasn't. I then asked what happens if and when it happens again. He told me to just work the other features like he did. We shall see what happens next time I bring it in.

Sorry but he's wrong, it's not fixed. It may be temporarily jolted back into working, but the gears and motor mechanism WILL fail if you continue to use it. This isn't an isolated case, many W204s have this issue and the fact is that your service advisor just doesn't want to deal with the actual repair. Which, btw, they'd be happy to charge you about $2,500 to fix if you were out of warranty.

Unfortunately, these are just not very robust parts on the W204/X204 platform. In fact, I'd say the steering wheel mechanism, the COMAND knob, and the electric steering column lock are among the highest failure items on this platform. If it were me, I'd insist they replace it and not just advise that I get jiggy with it when it acts up; that's not a fix.

And word to the wise: I don't know which Chicagoland dealer you went to, but stay the heck away from Hoffman Estates MB.

I followed your sugestion hit the steering wheel on the top. The wheel started to work again then I dissabled easy entry in the menue.
Now my wife is happy again...Priceless
Thanks again....Steve

Haven't been around for a while but just wanted to let the forum know my problem has since been resolved. Since moving to Arizona, Tucson Mercedes didn't even question the operation of the wheel. When I explained this was the third time it has happened, they gave me a loaner and sent me off. I came back to a new motor for the steering wheel and called it a day. Guess things are different out here versus Chicago.

That's more like it!

andreigbs

It's great that you found a good one. A lot of crooks in Schitcagoland.
I think it was more a matter of the plastic gear that broke and made the motor stuck. The updated parts are (hopefully) metal. Either way, I'd leave the "easy entry/exit" convenience option turned off.
Enjoy the dry heat

That actually worked😆
