Hi Mate
Couldn't help not to tell you that all of those errors I was getting for O2 Sensors and fuel consumption had nothing to do with the sensors. Had my car checked by a guy who wasn't even a professional mechanic. He was a bora ex-owner and had some parts and wires in his garage.
He checked all the wires and replaced some, it runs much better now with a fuel consumption of at least 500 KM per tank in city.

I was getting 350 KM before
