Review on IE Works Intake Manifold ALUMINUM Repair Kit for Mercedes-Benz Engine (V6 3.0L / 3.5L M272) (V8 4.7L / 5.5L M273) - Runner Air Flap Lever Throttle W203 C216 C209 C207 W201 W463 X164 X204 by Brian Trotter

Looks like a good kit comes with no central screw which I'm told usually breaks off when removed. I only found this out after I opened the package and couldn't find the instructions. So I searched for videos and found numerous references to the center screw being damaged during removal. Looks like I'll have to cut off the plastic lever on the old piston to install the part that ieworks sold me. Getting it wrong can result in the stroke position being wrong, which can cause it to crash again, or CEL highlights when it doesn't move to the correct position. I'm not impressed. :(
