Replacing O2 Sensor

[PJorgen]

Car is an '09 Carrera 2S with PDK. I have a recurring CEL that comes up with code P2414, which means a bad O2 sensor 1 on bank 1.

How difficult is it to replace this sensor? I'm not even sure exactly where it is. Any idea what a dealer would charge to do the work?

Should be on top of the cat on that side (bank 1 is left side of car) - the sensor closest to the header manifold.

Got it, thanks. Just realized that the car is still under warranty. Not sure if O2 sensors are included, but I'll probably start there.

In the US emissions parts carry longer warranties - check you warranty book.

Checked the warranty book and am very confused. The main 4yr/50k mile warranty specifically excludeds anything covered by the emission control warranty, of which there are many. The only place where O2 sensors are mentioned is in the federal 2yr/24k mile emission warranty.

The California 3yr/50k and 7yr/70k emission warranties do not mention O2 sensors, so are the O2 sensors included or not?. As I said, very confusing.

Will talk to the dealer and find out.

Won't hurt to ask?

It's at the dealer today, bad O2 sensor, covered by the standard 4yr/50k mile warranty. Will be replaced at no charge!
