Antipollution Fault Error

I have the same vehicle and this warning comes in a few months or a few weeks, it fixes itself after a day or two, it does not give any warning, many reasons have been given, I have not researched anymore, I have had the vehicle for 3 years and this is something that has been constant since I first bought it, interesting thing is, I have no problem complaints with my vehicle. just this warning comes up. You said you fixed this bug, but after a few months or even 1 year you can't be sure, such a damn thing
