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.
