Well the one I bought (8951) has a 14-day warranty on it, so I can just send it back to get my money back, then re-order the 0679 from Parts.com and hopefully my troubles will be over. Only thing I'd be out unfortunately was the shipping (I overnighted it here originally for $35, and then I'm gonna obviously have to pay ~$10 bucks to ship it back).

Either way it still beats the $450 price tag my shop was asking...

So for you, it was as simple as buying the part and re-plugging it in basically? Then full functionality came back?

Thanks

Just under four years ('09 but built in late '08) and my "scroll" no longer works. Everything else works fine. Glad to see that it is an easy fix.

Just to join the crowd, mine has just stopped. Car was made in July 2008 - just 4 years!!
Mercedes Benz had no suggestions as to how to repair it. I have an extended warranty with the car, but, don't know whether it would cover this?

Hi guys,

I've solved the problem with the comand knob.
It's not an easy fix, but it's doable

Solid post. Thanks. Saved for future reference.

WTF, my knob worked perfectly earlier today. Parked the car, came back and it doesn't work. I'm pissed. Here I am two months in to my first benz (bought an '08 used) and I'm having a problem. I'm not sure if I should fork over the cash to a dealer or just deal with it. Still have the horizontal movement, but as others said no scrolling/rotating is recognized. So everyone that took it to a dealer has gotten it fixed? How much in total?

just bought one from ebay, let's see how it works

Warranty expired yesterday at 50000 miles, knob stopped scrolling. It's almost comical. It's like it was programed to die. But I am happy, it's been a 50000 miles trouble free perfection of a car. Love my 2009 C350.

Add me to the list. Right after my wife dropped her purse on it yesterday it went kaput. Don't really mind spending the money for the part but will at least attempt a repair just to spite the obvious overpricing of it.

You'd think they'd at least quietly offer the part for a reasonable price if they won't admit and own up to the control being failure prone. Few would complain or even mention the problem if it were a $50 part.

Maybe I just have too much faith in companies having the integrity to stand behind their products beyond that magical warranty cut off where they suddenly become your enemy instead of your friend. They should realize today's MB owners, warranty or not, are tomorrow's MB purchasers when it comes time to replace or upgrade.

Mine has been out for awhile now. 2008 C300. Expired warranty! Took it to the shop for other reasons today, but had them look at the control knob. They asked for $500 to replace it. No thanks. for $500 it works perfectly not scrolling. I will try to fix it this weekend myself.

The wifes one failed with 12 weeks left of the warranty..whoop whoop a happy boy..now swapped for nothing, close shave

Mine quit working a while ago, dealt with it for a bit until I remembered that I purchased an extended warranty from CarMax. $450 fix done with no cost to me! Funny thing is, they did it really fast because they had another car in the shop for the same issue and just used the one they ordered for that one to get me in and out quick.

Mine broke last week. 4 years and one month old

Forgive me for being confused. Which part in conclusion (above) is the one I should order if I am trying to have someone fix my (2008-W204 with Premium Sound/DVD/BT/Nav)? Is it the one above ending in "8951?

Also, any idea where I can find an Item# 2048704890
iPod interface kit? Apparently they are sold out in Germany (MB).
Thank you for any response. I appreciate it.

dolphinman

The one you are recommending is Part number 2048700679 on parts.com? Thank you. Sorry for any redundancy....

This identical thing happened to me this week....luckily I have the extended warranty so no cash out of my pocket. The service advisor mentioned that this is happening more and more.

livestrong191

Yup mine is Ka-put too. No scrollie scrollie and the clear button Ka-put too

My control knob went dead a few days ago too, won't scroll anymore...just shy of 5 years...

I just wanted to add another dead scroll wheel to the count and that the latest part number 2048700679 indeed does work on an 08 C300. The latest part (second revision; third part number) on startek is 2048707558, but giving that part number to our local dealer yeilded the 0679 number above, so I went with it. Figured newer was better.

Cost was $203, online price was $190, $13 bucks was worth getting it immediately. Original price at the dealer was $226, but I asked for a discount and the guy behind the counter gave it. Looks like I caught him on a good day.

All in all about 30 minutes if you have the tools (torx drivers, composite pry tools, etc.) and you follow this guide, even faster if you just cut the cable to the old switch unit.

Mine crapped out as well a few months ago, 09 c63, about 4 years old I guess based on delivery date. Covered under CPO warranty though.

As for designed to fail, I doubt it, more like poor materials and sub par design. MB does not make the part, its made under contract from whoever came in cheapest at the time that they were needed, and purchased in serious bulk quantities.

They are also probably used about the same amount by everyone who daily drives their vehicles, which means the time to wear the parts out is going to be the same.

But does MB have QA?

You guys should all feel lucky about paying under $300 for this part. My mb dealer up here in canada wants $407 just for the damn part! Wtf!! And half the suppliers in the states won't ship to Canada. Awesome! I love getting dry fisted. It's the best! Lol! Cheapest I found it online was $180. But once again won't ship here. Best I can get is $280 + shipping + duty from the states or buy a used one locally for $110. Once the guy gets one of course. Ugh!

Out of my two 2011 MB cars, the first knob has just stopped working. You can navigate up-down, left-right but not scroll in any direction. Much to my surprise after reading many of your posts, I'm about to run out of warranty so I better take it for service.
MB should provide some sort of explanation to us customers, these are not $100 toys; after your house, your car can be the 2nd largest investment in your life.
