BRAND NEW *OEM Quality* mass airflow sensor to suit BMW 1, 3 and 5 Series and Z4 with the N52, N54 and M54 six-cylinder petrol engines.

When the MAF on a six-cylinder BMW starts to drift you get a rough idle, lean codes and a flat spot that no amount of cleaning fixes. This insert-type replacement slots into your existing housing and is packed and shipped from Cranbourne VIC.

PACKAGE INCLUDES

1 x BRAND NEW mass airflow sensor - insert only with seal ring, 5-pin connector and integrated air temperature sensor, 12V. Fits your original MAF housing.

ABOUT THIS SENSOR

This Continental/VDO-pattern hot-film sensor reads air mass and intake temperature for the DME on BMW's N52 and N54 six-cylinders and the late M54. Because it is an insert rather than a complete housing, it is a straight swap into the existing intake.

A worn element under-reads airflow, so the engine leans out and the DME pushes fuel trims to the limit - typically logging P0171 and P0174. Matched to the OEM part number and backed by our returns policy.

COMMON SYMPTOMS OF FAILURE

Check engine light - fault codes P0100 P0101 P0102 P0103 (MAF circuit)
Lean codes P0171 and P0174 on both banks
Rough or hunting idle
Hesitation on light throttle
Stalling when coming to a stop
Increased fuel consumption

Can I clean my MAF sensor instead of replacing it?

Yes - if the sensor is contaminated rather than electrically failed, cleaning with a dedicated MAF sensor cleaner spray can restore correct readings. Do not use brake cleaner or generic electrical contact cleaner as these leave residue that damages the sensing wire. Allow the sensor to dry completely before reinstalling. If cleaning does not resolve the fault codes, the sensor requires replacement.

What is the difference between a MAF sensor and a MAP sensor?

A MAF (Mass Air Flow) sensor directly measures the mass of air entering the engine using a hot wire element in the intake. A MAP (Manifold Absolute Pressure) sensor measures intake manifold pressure to calculate air density. Most modern engines use one or the other - some use both. Your vehicle service manual or OBD2 fault codes will confirm which sensor type your engine uses.

Will a faulty MAF sensor cause my vehicle to fail an emissions test?

Yes. A faulty MAF sensor causes the ECU to miscalculate fuel delivery, typically resulting in a rich running condition that increases CO and hydrocarbon emissions. Most roadworthy and emissions checks will fail a vehicle with an active MAF sensor fault code or visibly excessive exhaust smoke.

What are the symptoms of a bad MAF sensor?

Common symptoms include rough idle, hesitation or stumbling on acceleration, poor fuel economy, black smoke from the exhaust, and an illuminated Check Engine light. Your ECU may log fault codes P0100 to P0104.

Can I drive with a faulty MAF sensor?

You can drive short distances but it is not recommended. A faulty MAF sensor causes the ECU to run incorrect fuel mixtures, which can damage the catalytic converter and O2 sensors over time. Have it replaced as soon as possible.

How do I test if my MAF sensor is bad?

Use an OBD2 scanner to check for fault codes P0100-P0104. You can also use a multimeter or live data scanner to check the sensor output voltage against your vehicle's specification. A reading significantly outside spec confirms a faulty sensor.

What causes a MAF sensor to fail?

The most common causes are a dirty or contaminated sensing element (often from a missing or damaged air filter), oil contamination from an over-oiled aftermarket air filter, heat damage, or general wear over time.

Do I need to reset my ECU after replacing the MAF sensor?

It is good practice to clear any stored fault codes using an OBD2 scanner after replacement. Some vehicles will self-adapt within a short drive cycle, but clearing codes ensures the ECU recalibrates from a clean baseline.
