A3 8V 2.0 2014 error codes

[hater]

Hi everyone,
I recently bought Audi A3 and I am veeery satisfied about it. Running very smooth and don't have any problems but, recently yellow engine bulb on instrument table pops up. Nothing else happened and the car is driving fine but the bulb is still there. I connected VCDS and see all the trouble codes and got this. Any help would be great.
Thank you

Looking over the internet found out that most of the codes over engine are caused by O2 sensor(lambda). I reset the codes and everything is fine for now. No more yellow bulb.

So after a few days yellow bulb pumps again. Finally bought a new O2 sensor 03L 906 262 and reset the fault code. Driving now for 100km and nothing pops up. Think that solves the problem.
