This video shows you how to install a new mass air flow sensor from TRQ on your 2004-2009 Audi A4 Quattro (2.0L L4). The Mass Air Flow (MAF) sensor determines the mass flow rate of air entering your vehicle. A trouble code indicating the sensor is not working properly could be because it is dirty, malfunctioning, or damaged, in which case your vehicle may run poorly or enter limp mode. Fortunately, sensors are typically easy to replace.

This repair was done on a 2007 Audi A4 Quattro Base 2.0L Sedan 4-Door AWD Automatic and the process should be similar on the following vehicles:
2004 Audi A4 Quattro
