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. The idea is this helps better 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 getting your state's inspection.
Replacing the pump is pretty straight forward, and the key to fixing this on your X5 3.0 liter is to have the right part. This is air pump is made by the original equipment manufacturer (OEM) to BMW, and will give you many more years of operation.
This emissions air pump is for 2001, 2002 and 2003 model X5 3.0i (3.0 liter). X5's after 2003 use a different engine and different pump, so be sure to order with this in mind.
