Quality O2 Sensor
This does work for the rear position on a 2001 Jetta 1.8T AWD, even though it says it doesn't. The AWW and AWP uses this in the rear and has the same ECU as the AWD. The only difference is this sensor has a longer wiring lead. Also they say the AWD rear sensor can be tapped for an Air Fuel ratio gauge, but I don't see why this one couldn't be too. The wire colors, connector, and sensor look exactly the same, so unless the internals are different not allowing a gauge. However, this did work in the rear position on my AWD.
