New Engine Knock Sensor from 1AAuto.com https://trq.video/ib-1AEKS00018

This video shows you how to install a new knock sensor in your 2004-2009 Audi A4 Quattro 2.0L I4. A knock sensor monitors your vehicle’s engine for unusual pulsations caused by things such as engine knock. If a sensor is damaged or malfunctioning, the engine may run poorly, inefficiently, or only in a low speed safe mode, and may also trigger diagnostic codes.

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
2005 Audi A4 Quattro
2006 Audi A4 Quattro
2007 Audi A4 Quattro
2008 Audi A4 Quattro
2009 Audi A4 Quattro
