Replacing the Mass Air Flow Sensor on Audi A4

Model: Audi A4 B5 - Years 1994-2000
Part: MAF sensor

With the car off and the parking brake engaged, lift the hood and secure it. Remove the air duct located on the front right (to your left) of the engine bay. Using a Phillips screwdriver, remove the bolts securing the panel shown in the video, then disconnect the air duct housing from the engine air filter box (to do this, you need to unscrew the clamps and detach the connector). Remove the bolts related to the mass air flow sensor housing and replace the sensor. Work in reverse order until fully reassembled, and you're done. Good luck!
