I noticed that one of my wheel caps had fallen apart. So here is a simple DIY on how to change your center cap.

Tools needed: 1. Knife
2. Center cap (Part# A 171 400 01 25 5337) for 2010 E550. (your center cap may vary)



Take your knife and pull off the center cap.



As you can see in the picture, the new center cap needs to be pressed in.



Align the center cap to the rim.



Press in until it's completely inserted.




Done!

Thanks for the DIY. Gotta be careful with the knife so you dont scratch the finish on your wheels though. I prefer to take the rim off and punch out the centercap with the plastic handle of a screwdriver.

I do wheel removal as well. Having floor jack, powerful electric driver and torque wrench handy it takes me about 90 seconds to pull the wheel.
I tried knife/screwdriver approach in the past and most of the time broke tab on cap.
Sure if you are disposing old ones - you can drill hole in the center and put a hook on it.
This wheel is different from MB wheels I have, where cap if flush with the rim.
New caps don't have the spring rings?

Side note - the cap is still made in Germany.
Most of the MB original parts I am buying lately are coming from all over EU.
