Please note: We are seeing a high rate of failure on secondary air pumps due to failure of the secondary air pump valve. This causes exhaust contamination of the pump and premature failure. A new valve, part number 11 72 1 435 420, must be purchased at the time of the secondary air pump sale to validate the 1-year warranty.

Attention AWD 325xi/330xi owners: We have noticed a number of cars after the 3/2003 production split using the earlier secondary air pump and valve setup. Please check your vehicle prior to ordering. The older system has a second vacuum line coming off the secondary air valve and the hose between the valve and the secondary air pump uses conventional hose clamps. The later system has no vacuum line off the valve and the hose between the valve and the secondary air pump is held in place with quick-connect fittings.
