Jun 5, 2019 at 0:14 comment added Salvador Martinez @Ben I have attached my logging. Not sure why bank 1 sensor 2 is sporadic I expected bank 1 sensor 1 to be the one at the front.

Jun 4, 2019 at 2:17 comment added Ben Post cat o2 sensors can be used for final fuel trim adjustment as well as a way to verify catalyst operation. You might want to do some data logging to see what’s going on with your fuel trims and o2 sensors.

Jun 3, 2019 at 18:53 comment added Salvador Martinez Hi Mike, I had a P0420 code and had replaced all 3 oxygen sensors on my car. Some people have managed to get rid of that cat inefficiency with a spacer. When I bought the car 10,000 miles ago we had installed a new universal rear cat, not knowing that there was another one near the turbo. Front Cat is not sold separately and the part 3C0254506EX comes with both converters from vw but is $1,000.
