MAF AIR FLOW SENSOR 13712247002 0928400314 (03-05) FOR BMW 318 TD TOURING (E46)

MAF Air Flow Sensor for BMW

This mass air flow sensor measures intake air volume so the engine control unit can deliver the correct fuel charge, and it cross-references OEM numbers 13712247002 and 0928400314.

Overview

This MAF air flow sensor is a direct-fit replacement for the factory meter on BMW 318 TD Touring (E46) models built from 2003 through 2005. It restores accurate air metering so the ECU can balance fuel trim, idle quality, and throttle response. Install it when a failed sensor brings on a check engine light, rough running, or poor fuel economy.

Specs At A Glance

Good To Know

Q: Will this sensor need coding after installation? A: No coding is required on this application. Clear the stored fault codes after fitting and let the ECU relearn fuel trim over the first few drive cycles.

Q: How do I know my old sensor is the problem? A: Common signs include a check engine light, lean or rich fuel codes, hesitation, and reduced power. Confirm live air flow readings against spec before ordering.

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