antipolition fault error

My 2002 model 307 xr vehicle gave an antipolition fault error 1 week ago, the yellow engine light came on today and it turns on today.

I thought it was a malfunction:
1-catalytic converter blocked
2-oxygen sensors faulty
3 - ????

what do you think i should do .......

my friend, once i bought diesel from po because i couldn't find shell in datça, i encountered this warning. It may be due to malfunction but in general, the perceiver in the exhaust gives this warning by perceiving that the smoke coming out is different or dirty due to the fuel. Let me tell you, this problem (not exactly a problem). Every service says every master says something different.

Yes, I agree with Mabolla. It happened to me. The friends in the forum said that it could be poor quality fuel. On the day of the malfunction, I bought fuel from a place where it was not busy. When I used the car, the fault lamp remained on for a day. Be careful.

It is necessary to be careful not to burn the fuel indicator light as much as possible, especially in diesel vehicles. Because the dirty fuel stays at the bottom, it may encounter this warning. I have not burned that light even once.

Is it possible that this problem is caused by fuel when the antipollution fault error is lit in gasoline cars? . I always buy gas from the same place, but yesterday this fault light came on. There is no drop in performance. The fault light went out when the ignition was on and off, but I never tried again. my car was 2002 296 gti. I am waiting for your comments.

If there is a leak in the exhaust or a performance exhaust, the probability of giving this error is high. My friend has 206 cc escapes his exhaust and has been giving this error since then. Master said so.

The same problem is in my lion, Hakan. Mine is 307 xr gasoline. I went to the service and got the machine connected. The guys called me a catalyst. I went to empty the catalyst. It didn't work. I was in vain from the catalyst. Then I read his book a little, when he was from the catalyst, he was already writing as a catalyst. this antipollution failure happened when there was a problem with the air systems. (writes in his book). I renewed the air filter, cleaned the throat butterfly cleanly, but it is still on fire. a friend of mine may have an air flow meter problem said clean. it was also on my mind. I will have it cleaned now. But keep in mind mine is gasoline. If yours is diesel, there may be another problem.

this warning is burning in many mistakes, fueling from different places, going from the bottom of the dirt on the dusty road is like changing the diesel filter for a long time, but it was burnt in the outside of the diesel filter, but it is late after a few hours.

Look, I went today and got the machine connected, and the connected machine is better than the authorized service. what happened under that famous "antipollution fault" message:

The same model is available to me in 307, my dear friend. I had the computer connected in the service 2 times. In the first, they said the cursory oxygen probe (sensor) was malfunctioning when buying. The second was called the back oxygen probe. Then the particle took this part and put it together in a special mechanic. I didn't give the light 30 TL because I was thinking of getting LPG on the vehicle and the LPG master said I would turn off the light. But the light went out on its own within 2 days, the error also went away. So my advice would be to connect the computer to 30 TL repairers in 60 TL services and get the net error. Good luck with.....
