Frequently Asked Questions (FAQs)

Q1: How do I check if this MAF sensor fits my BMW?
A1: Confirm your vehicle’s model, engine and production years. This sensor fits BMW 3 Series with the N47 D20/N47 D20 C engines (316d, 318d, 320d) across E90, E91, E92, E93 generations (approximately 2007-2013), and BMW X1 (E84) diesel models with the same engine family (2009-2015).
Next, check your old sensor’s OEM part numbers: 13628506409, 0 281 006 093 or 8506409. Matching these confirms compatibility. 
If you’re unsure, supply your VIN or registration via the “Find Part” tool on the site for verification.

Q2: What are the symptoms of a failing MAF sensor in these BMWs?
A2: Common signs include:

• Rough or fluctuating idle (engine hunting)

• Loss of power, especially under acceleration

• Increased fuel consumption

• Check-Engine light (fault codes related to airflow/MAF)
  Because the MAF sensor tells the ECU how much air is entering the engine, inaccurate readings lead to poor engine performance.

Q3: Is cleaning the existing sensor an option or should I replace it?
A3: Cleaning can sometimes restore function if the sensor is simply contaminated (e.g., from oil or filter leakage). However, if the connector is damaged, the readings are erratic, or fault codes persist after cleaning, replacement is recommended. Since the listing describes an “OEM quality aftermarket part” it offers a reliable labor-saving upgrade.

Q4: Does installation of this MAF require special tools or coding?
A4: Installation is generally straightforward: disconnect the negative battery terminal, remove the air-intake duct, swap the sensor (ensuring correct orientation and secure connector), clear any stored faults and allow the engine to relearn. No special coding is usually required unless your vehicle’s ECU mandates it. Ensure proper sealing to avoid introducing unmeasured air leaks.

Q5: What warranty and shipping terms apply?
A5: This sensor is shipped from UK-based stock with free shipping on all orders. The product is backed by a 12-month “worry-free” warranty covering manufacturing defects, provided the part is installed correctly and used under normal conditions
