Hi guys, I have a Polo 6C 2015, Engine: 1.6 MPI (CWVB). 108000km rolled.
Engine scan found this:
download/file.php?id=4794&t=1
download/file.php?id=4795&t=1
download/file.php?id=4796&t=1

What should I do please?

Justly, I don't understand what does the error code mean.

Ok, well i cant understand the language on your VCDS Scan, but acording to what i think, it might be a issue with your O2 sensor that i belive is the one between the First and second cat, i would just have a look there and see if its a noticeable issue then just change the O2 senor, i think its about 20 to 40 Eur.
