Also I found a repair kit https://www.aliexpress.com/w/wholesale-nox-sensor-repair-kit.html?spm=a2g0o.detail.search.0

so, at the end, replacing the sensor is the solution

Also, when I reset the error, the car automatically starts regenerating the particle filter.

I don't know how is sounds, but I don't trust the guys from Škoda. What I mean, they won't try to clean it, is easier to replace it. As long as I need to replace it, I think is a good option, trying to clean it first.

I've seen on YouTube, they clean the sensor with radiator cleaner. What do you think?

Probably changing the sensor is the key for a while, the thing is, If you drive in the city the error will come back I don't know where we can find the best price for this

Yes, MiniOBD II. I didn't use any software until now to clear the eror, only at Skoda every 10000 when I was changing the oil. Sometimes, the error disappeared by itself. But rarely

Is P2200 2-3 days, depends

Hello guys! I'm facing the same problem with a Skoda Superb III 2019, 2.0 DSG 4X4 190hp. Didn't know at the beginning with be long lasting issue. It appears from the firt 40.000km, and now at I'm at 190.000. No loss power or something, just the error.
