Today we will show you how to replace your MAF sensor on the CHEAP! Watch the video or read the tutorial below. Enjoy!




Start by purchasing a Volkswagen MAF sensor, it has the same sensor as the BMW but different housing. Here is the part for reference:

 


Start by removing the MAF sensor from the VW housing. You will need a 5 star tamper resistant star bit set to move the screws holding in the sensor.


Actual bit size to remove the sensor is a T25




Unclip the stock sensor by pressing on the sides and pulling up.




BMW uses a 6-point tamper resistant torx bit.



Old vs. New:



Make sure the orientation of the MAF sensor is correct.



Plug it in.



Start your car, it usually takes a few minutes for everything to reset it self. Or use a OBD tool or disconnect your battery for 10 minutes to restart.
