Razor Sharp Steering Wheel
It's a 2010 E350 4-Matic. Any chance of dealer coverage? After removing the band aid that protected our hands,
the edge stood up 1/8" best seen in the left hand close up, although visible in the right hand shot as well.
I removed the sharp edge, so now it's safe. This sort of issue is disappointing.




Dealer will be happy to cover any of this with a swipe of card.

The part number is MERCEDES-BENZ 09946400139107. There are many aftermarket ones which come in gloss black, carbon fiber, etc available on eBay. Got mine via Amazon.
To change the trim, you will need to remove the airbag. You MUST disconnect the battery and allow the air bag is discharge for 10-15 minutes before removing it to avoid an SRS warning light. Youtube has videos on how to remove the airbag, basically poking two holes on the back of the steering wheel to toggle two latches, one on each side of the wheel which allow the airbag assembly to be removed. Try to keep the hole you poke as small as possible. Another bad Mercedes design.
Once unlatched, hold the airbag assembly forward and disconnect the harnesses. Place it carefully somewhere safe, so it’s not damaged. The trim piece can be unscrewed from the from front two screws being the air bag, and two screws accessible from behind the steering wheel. (See pics below).
Unclip the steering wheel controls and unscrew from the trim piece. Exchange the steering wheel controls to the new trim and start to install the new trim on the wheel. Make sure that the wires don’t cross into the airbag space and be super careful that the lower screw prongs on the steering wheel align right with the screws so they don’t snap off. (See Below).
Once everything is screwed and the trim piece is installed, plug in the airbag. All the plugs are color and shape matched. The airbag clips in, you’ll hear each side engage. Reconnect the car battery, start the car with the doors closed. Let it run for 5 mins and test steering wheel buttons to confirm functionality. I hope this helps.
Use a long small screw driver to access the airbag prongs. Additionally, the trim piece is help in by two front screws, accessible being the airbag and two back screws accessible behind the steering wheel.
Be carful with these two prongs. Make sure the screw lines up and not to over screw when installing the trim on the wheel. I broke one off which required me to plastic epoxy it back together and pray. It held up extremely well but would be better to avoid my struggle.
Small hole to access the airbag prong clip. You'll feel an indent guiding you where to stab. Horrible design, since once its made, you can really repair without replacing the back cover. I have a some electrical tape to cover it. Super tacky but beats getting slashed while driving.
