Common source of emission related issues

Your BMW's secondary air injection pump turns on when you start your car from a cold start. It injects air into the cylinder head to help burn up excess fuel and to reduce emissions. A failed secondary air injection pump can result in a CEL as well as other emissions related problems. We also recommend inspecting the hoses leading from the air injection pump to the air injection valve as these are known to crack.

FCP recommends ordering new mounts for this air pump to ensure an easy installation. Please see p/n 11727559515 for the correct mount, 3 are needed in total. Also replace the secondary air pump relay, p/n 12631742690.
