This part is listed by BMW as BMW part number 11721437700 (11 72 1 437 700) and is described as an Genuine BMW Secondary Air Pump for 2000-2003 E53 X5 3.0i. These pumps are sometimes called auxiliary air pumps or smog pumps, as they are emissions related equipment.

Are you getting a check engine light and faults codes pointing to your secondary air injection pump? The secondary air pump is an emissions pump that pumps fresh air into the exhaust during cold starts. This helps burn fuel on a cold engine, and when the pump runs it sounds like a little vacuum cleaner under your hood. When this pump fails, the pump doesn't cycle and the emissions control computer records a fault, triggering a check engine light. This will make you fail an emissions test, and may prevent you from passing a state emissions inspection.

This is a Genuine BMW air pump with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.

This part number replaces previous BMW part number 11721437911.
