Specs At A Glance

Good To Know

Q: Will this sensor need coding after installation? A: Most BMW diesel MAF sensors are plug-and-play, but clearing stored fault codes after fitting is recommended. Q: How can I tell if my mass air flow sensor has failed? A: Common signs include rough idle, reduced power, black smoke, and MAF-related diagnostic codes on a scan tool.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
