This BMW secondary air pump (OEM 7557903) is a used genuine part. Also known as an air injection pump, it forces fresh air into the exhaust during cold starts to accelerate catalyst warm-up and reduce emissions. Common failure symptoms include a check engine light for insufficient secondary air flow or a noisy, seized pump. This pump fits BMW 128i, 328i, 328i xDrive, and 328xi models with the 2.0L turbo (N20) or 3.0L naturally aspirated (N52) inline engines.
