I replaced mine yesterday with an Aluminum one. Seems to be back to working condition. Two things that I wanted to ask:

1. This Aluminum replacement seems to cause more resistance as I believe it should or is this just in my head?
2. I scratched the ring that comes off when you remove the knob off of the controller. Does anyone know if that's a piece that is replaceable by itself?

Same here,

If you can send me the file so that I can print it. Currently trying to gorilla glue the shaft right now and still debating if I need to buy the alum. version of the shaft.

I was scrolling through music really fast and it broke and would not scroll anymore. Luckily I still had like 1000miles of warranty so they are replacing it.

Solution From USA

The plastic internal shaft has a breaking point. Not sure if this was designed as preventive measure to save the entire unit from breaking or just sneaky planned obsolescence.

There is a seller in USA who also offers an upgraded aluminium shaft.
Attached is a helpful PDF file on how to do the replacement.

They have it on Amazon Prime too IE Works Replacement Shaft

Thought Id go ahead and add mine to the list, as it failed a couple weeks ago. My 08 c300 lasted almost 10 years, unless the previous owner changed it out already.

Anyone else have the ribbon cable run behind & underneath the center console making it impossible to remove the knob module without removing the center console?

You don't need to remove the console. Just push the chair back and reach between the console and carpet and use your fingers to push the wires towards the passenger seat. The have a lot of patience in wiggling the entire wire out from the small hook below the console. It will come out eventually. Then when you are putting it back just run the ribbon on the biggest rectangular opening below the console.

do you mind posting a picture of what you mean? It sounds like I need to stick my fingers under the center console and push the wires out through the passenger side. Then i can disconnect the ribbon from there?

Not being the least but sarcastic, but you must have really tiny fingers...

Unless.... do you use something like a screwdriver shaft to lift the edge of the console away from the carpet?

I had the same problem as you, the ribbon seemed to be really wedged in and near impossible to get out. What I did instead was slowly wiggle the wires loose so I could pull the COMAND knob assembly out a bit and I disassembled it, and replaced the shaft inside the car with the ribbon still connected. You'll have to be careful if you do this because there are lots of small parts, but it certainly beats having to wrangle the entire assembly out of the car in my opinion.

I just scraped my two fingers and a lot of swearing! Best is to wear surgical gloves so that you won't scrape the fingers and finger the hell out of the cable LOL! What I did is push the carpet inward rather than pulling the plastic console towards the driver seat. The carpet has a tough linear at the back but it will give and don't worry about ripping it as it won't just don't insert anything other than your two fingers.

Just be patient. again you need to push sideways towards the right passenger seat and it will just slide. when you manage o get it out do not put it back. Just tape it on the side so that it won't move and rattle with the shifter assembly

NO NEED TO CUT THE FACTORY WIRE ..THATS A NO NO IN MY BOOK
JUST FOLLOW THE WIRE AND UNHOOK IT FROM THE SIDE PASSENGER CARPET AS SHOWN IN THIS CLIP


YOU DO NOT HAVE TO REMOVE THE GEARBOX... JUST FOLLOW THE CABLE..IT WOULDN'T MAKE SENSE TO REMOVE THE ENTIRE GEAR BOX JUST TO GET TOT THE CABLE
