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 Steven Thelin

It worked great but I warn you if your arm is broken make sure you know why it is broken. If internal parts stick and rupture, the plastic inside can crack and cause catastrophic engine damage. That's why Mercedes suggests replacing the entire manifold. This will work and save you money, but make sure your wings are working freely and aren't cracked.
