Hi all, My daughter's 2011 C300 (90K) had a check engine light with a code P0410 indicating an issue with the secondary air pump. I replaced the secondary pump (which was evidently seized) and reset the code. Drove it about 50 miles with no check engine light so I returned the car and started a vacation about 4 hours away. She drove the car and a few hours ago and the check engine light came back with the same code. Should I have replaced the relay and fuse too? The fuse looked fine when I checked it before the repair. Does anyone have a schematic of the engine fuse box which lists the fuse and relay locations? I can't seem to locate a good one online. I have the fuse and relay so I could have her replace them and reset the code to see if that fixes the problem before I return in a week. The secondary air pump was replaced 6 years and 60K ago by the dealer under warranty. Is this a common problem? Thanks in advance for any assistance!
