Has anyone run into issues with code P0415? Any suggestions or help is appreciated. This is my first benz. Trying to get it to pass smog.

 

P0415, I believe that is the Secondary Air Injection System Switching Valve Circuit Malfunction, or Air Vacuum Control Solenoid Circuit Malfunction. Could be the Air Pump is inoperative, or the bypass solenoid has a bad connection or itself is bad. If you're a DIY guy then try this video.
If you're not a DIY Guy, bring it in to your dealer or specialty shop and let them know your engine light is on and need an inspection. My dealership has a labor rate of $175/hour, you can use that as a baseline for whatever dealership you use. Good luck
