Hello , new to this forum. My wife's 2003 SLK 230 Kompressor runs great , No engine miss or hesitation. The car keeps getting diagnostic code po410, I can delete the code but it comes back after a while on an engine restart ,The code indicates a problem with the air pump, however the car doesn't have an air pump, It has a supercharge that seems to work fine. I checked the diverter valve solenoid and it seems to function properly.
There doesn't seem to be any secondary air leakage between the supercharger and the throttle body The car has 44,000 miles The only other sensor at the end of the line would be the oxygen sensor, but I don't get the code that the oxygen sensor is defective. I am looking for any comments pertaining to this malfunction. Thanks
