2003 Audi A6 Quattro 3.0L MIL Lamp on
Posted to European Driveability on 9/9/2009 8 Replies

Need help from experienced Audi or Euro tech. The B1S1 O2 sensor heater tests bad. How on earth do you get it out? I can see it, cant touch it or see how you could get a socket on it. There must be a way, what do I need to remove to get to it?
