P2196 Error Code on Octavia mk3 1.4 tsi 140 hp

Hi all,

Today, while driving, my octavia's check engine light came on, plugged it in to an OBD scanner and it said:

P2196 -> O2 Sensor Signal Biased/Stuck Rick bank 1 Sensor 1

I must mention, that earlier in the week I happened to notice that when I start the engine on, and the AC starts running, I can feel a smell of gasoline coming in through the vents.

I checked online it says that it can be a high pressure fuel pump problem, or something completely different.

I am open and thankful to suggestions, since this is the first time I experiencing this type of problem.

Is it safe for me to drive the car?

Should I immediately leave it at the workshop?

Or what more could I check?

Is it a common thing with these Octavias?

The car has 133 000 kms on it.

Thanks in advance.
