About 308 vti catalyst failure

Hello again. Our current adventure regarding my automatic 308vti vehicle in 2008 model 160000 is about the engine system management fault warning. My vehicle stayed at the authorized service for about 1 month)

-I didn't experience any misfire or gas rushing when this warning appeared on the screen.

-I couldn't get the error code when I had it connected to the device, but the authorized person was just a catalyst He said that it gave a malfunction and it should be replaced with the original one. He stated that I would get the warning about the error again in catalyst repairs. Has anyone ever had a catalyst repair and had a negative situation?

hello

Particle filter was clogged in our 308, liquid serum was changed, something else was done, we gave a total of 800 TL, nothing was solved, particle error is over, after changing the liquid serum, system management gives faulty error 700-800 When I get the last gas on the steepest slopes, it gives it every time, we couldn't get it done yet, I didn't take it to the authorized service, I don't know how it will be fixed again. We did not have it done, because it is unknown even if we paid a lot of money.

Whether it's gasoline or diesel, the car is yours.4 It's like the car is dying while mine is going up the ramp. VALLA I've spent a lot of money on the car since 2017, but I still can't get the efficiency I want. When connected to the device, it says catalyst aging.

I detected something if I use the tool everyday, the catalyst error does not even appear for 2-3 days. But when I do not move for a few days The next day it gives this error even 3-4 times at the same time. Anyway, this is not a problem now. Now we have another problem
