Alright now i've had the code for awhile and i'm just getting around to fixing it. Took the covers off my engine and can clearly see the broken plastic actuator arm. What part would y'all recommend i replace this with? Definitely want an aftermarket metal one, just not sure which company. Also while I have the manifold off the car is there anything i should replace/ inspect while i'm at it? My car is an 07 c230 Sport Thanks!
