Just on a hunch, I tried google.

Advice: Use Google next time:
What does OBD-II fault code P0486 mean? EGR (Exhaust Gas Recirculation) systems are used to reduce the combustion temperature, thus reducing emissions. If the engine control module (PCM) does not detect the amount of flow requested from the EGR, it will set code P0486.
I do not believe that is a supported code in our platform, the Crossfire and SLK320 don't have an EGR "B" circuit. Of course, the manuals have a lot of errors, but I really don't think we have an EGR "B" circuit. What did you read that with?
