Out of interest, how much did they charge for that part? I was quoted over 300 quid from the nissan parts team

Qq J11, 1.6DCi, Automatic, 65 plate (warranty expired in January).

I have been struggling with what started as a P0136 error which i understand to be a O2 Sensor Circuit Malfunction Bank 1 Sensor 2, which i believe is post cat. I have not been able to find any information online as to 'where' this O2 sensor actually is.

I climbed under the car and found the sensor in the attached image. It is fitted to the top of the exhaust pipe about central just behind the front wheels so i assumed this was the correct sensor. The sensor is a 5-wire, but i see replacements come in both 4 and 5 wire. I removed it, gave it a clean with some sensor cleaner and reinstalled it. No improvement. I then got a replacement from ebay (after Nissan quoted me over £300 for the part alone) and fitted it. I now have a several more errors that I started with.

P0136 remains
P0141 New - O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2) – Downstream
P114D New - P114D - Post Catalyst Fuel Trim Via Oxygen Sensor System Too Lean Bank 2

Have i replaced the wrong part? Is anyone able to offer any advice or a picture on where the correct O2 sensor is located? I have spent around £50 on cleaner, tools and replacement part so far and have only managed to make the problem worse. I am completely defeated. Any assistance that anyone could offer would be greatly appreciated.
