Hey what's up guys? I have a 2000 C230 Kompressor and my check engine light periodically comes on. It comes on for a couple of days then go out for a couple of months. I finally hooked up a code scanner and got a code from the computer. It's saying "P0410 Secondary Air Injector Problem, Car OK To Drive". I never notice a change in how the car runs when the light is on. I think it might the mass air sensor but I'm not sure. Any ideas?!?
