Frequently Asked Questions (FAQs)

Q1: How can I check if this MAF sensor is the correct fit for my BMW?
A1: First, check your vehicle’s model, engine type and year — this sensor covers many BMW models such as 1-Series, 3-Series, 5-Series, 6-Series, X1, X3, X5 and Z4 where the OEM number corresponds (e.g., 5WK97508, 12806026076, 13627551638). Then, compare the part number on your old sensor. If the number matches or is listed on the product page, that’s a strong indicator of compatibility. For extra assurance, provide your VIN/registration via our “Find Part” tool or contact our support team for confirmation.

Q2: What are the common symptoms that your MAF sensor may be failing?
A2: Symptoms of a failing MAF sensor include rough or unstable idling, loss of power or sluggish acceleration, decreased fuel economy, “Check Engine” light illuminating with a code related to air-mass/airflow, black or rich exhaust smoke and transmission shift irregularities.
Proper diagnosis is recommended since other components (vacuum leaks, faulty air filter, intake boot damage) can cause similar symptoms.

Q3: Is cleaning the existing sensor an option instead of replacing it?
A3: In some cases, yes. If the sensor simply has contamination (dust, oil film) and the readings are borderline, cleaning with a proper MAF sensor cleaner might restore function. However, if the sensor’s internal element is damaged, connector wiring is corrupted, or fault codes persist after cleaning, replacement is the more reliable option. Proper fitment and calibration are key for accurate operation.

Q4: Does replacing this sensor require special tools or coding?
A4: Installation is generally straightforward: disconnect the battery, unplug the old sensor (typically located in the air intake between the airbox and throttle body), remove it, install the new sensor in the same orientation, reconnect wiring, clear any fault codes and allow the engine ECU to relearn. No major coding is usually required for most models, but ensure the connector and part number exactly match.

Q5: What warranty and shipping terms apply?
A5: This MAF sensor is shipped from UK stock and qualifies for free shipping (as per the website’s policy). It comes with a standard warranty covering manufacturing defects, provided the part is installed correctly and used under normal operating conditions. Keep your proof of purchase and follow installation guidance to retain warranty validity.
