Anyone have a link or reference for how to test O2 sensors on the B7 using VAG-COM? Was able to find some procedures on VWVortex but those pertained to the VR6 and 1.8T engine.

The first time I did the procedure driving, it's supposed to be in park. Puts the car in a pseudo limp mode where the acceleration is tapered.

Thanks allstock!
Im getting codes and CEL related to my post cat sensor (B1/S2). Going in for emissions and already will fail readiness on O2 sensor related to these codes. Hopefully just a bad sensor but my guess is it has to do with my RAI DP/HFC. J-pipe is installed on post-cat sensor in case someone mentions it.

btw, should the car be up to operating temperature when running these tests?

I don't remember waiting too long for 'ok' to show up and I commenced the procedure after the car was cooled down.
I'm sure 'ok' will appear when the correct temp is met as long as the sensors are copacetic.
So I'm assuming op temp should be better.
