C55 Secondary Air Pump P2002 P0410





my Check engine light comes on.

I changed the secondary air pump with a new unit and new relay. Erased the code. And it came back on.

Any idea what else’s it could be ?

Probably have a leak somewhere or the check valve is clogged and not able to operate properly. Check all the hoses for age or cracks and inspect the check valve.

Just to update this thread. The secondary air pump fuse was burnt.

Got it the fuse for $7 at the dealership and all is well.

Hope this helps someone in the future !
