AdvanEX Mass Air Flow Sensor MAF for BMW & Mini — Part 13627602038, Direct-Fit OE Replacement

The AdvanEX MAF 13627602038 is a direct-fit mass air flow sensor engineered to restore accurate air-measurement readings on compatible BMW and Mini Cooper models.

This replacement mass air flow (MAF) sensor is designed to match OE form and function for a wide range of BMW models and select Mini Coopers. It detects the volume of air entering the engine and relays that information to the engine control unit (ECU) so fuel delivery and ignition timing can be adjusted. Using the correct part number and following simple pre-installation checks helps avoid installation issues and supports reliable vehicle performance.

Which vehicles will accept this AdvanEX MAF sensor?

This MAF part is compatible with numerous BMW model years and certain Mini Cooper years. Confirm fitment by comparing the vehicle year, model, and original part number before ordering to ensure proper match and connector alignment.

• BMW examples: 2 Series (228i), 3 Series (320i, 328i), 4 Series (428i), 5 Series (528i), i8, M3/M4/M5/M6, X1/X3/X4/X5, Z4
• Mini: Compatible Mini Cooper model years listed in the fitment chart
• Replaces OE numbers including 13627602038 and 0280218266
• Use vehicle selector or contact seller to verify year/model fitment

How does installing a quality MAF sensor help engine operation?

A properly functioning MAF sensor supplies the ECU with precise air-flow data, which helps the engine manage fuel injection and combustion timing. This contributes to smoother idling, predictable throttle response, and consistent emissions control without claiming performance gains beyond restoring intended operation.

• Improves accuracy of air-to-fuel calculations
• Helps reduce engine hesitation and rough idle caused by faulty readings
• Supports stable cruise and acceleration behavior
• Works with factory engine management systems—no reprogramming required in most cases

What should I check before installing the replacement sensor?

Inspect surrounding wiring, connectors, and intake tubing to prevent repeat failures after installing the new unit. Also follow static safety guidelines and ensure the mating surfaces are clean to get a tight seal and reliable electrical contact.

• Examine wiring harness for frays or heat damage
• Confirm intake duct and clamps are intact and leak-free
• Perform static dissipation (grounding) before handling the sensor
• Test with a code scanner after install to confirm proper operation

How do I know this AdvanEX part is the right replacement?

Match the original part number and physical connector style to the AdvanEX unit to ensure a correct swap. If you aren’t certain, use the vehicle year/model drop-down on the product page or contact the seller with your VIN for verification.

• Replaces: 13627602038, MAS0338, 0280218266
• Direct-fit electrical connector and mounting points for listed vehicles
• Seller support available to confirm compatibility using VIN
• Follow post-installation checks and clear any stored codes

Who is this for: This AdvanEX MAF sensor is aimed at DIY mechanics, independent repair shops, and BMW/Mini owners who need a like-for-like replacement for a failing mass air flow sensor. It suits anyone who wants to restore factory air-measurement accuracy without modifying engine management systems—provided they verify compatibility with their specific model and perform recommended pre-installation inspections.
