That's your front Oxygen Sensor. It's in the down pipe just past the turbo outlet. Does it say the sensor is open, shorted, or below threshold?

I have a 225 (AMU) engine so it might be different than yours. Look between the firewall and engine. I'm sure someone can post a pic for you though.

Here is a picture from my Bentley manual, this is for a 1.8T non quattro. You didn't say what you had. Part #9 is what you're looking for.

It's roughly the same place, right after the turbo. In fact, it's even easier to reach. Just get a good O2 wrench and some long extensions. You're looking for #2 in this diagram.
