Dear friends, tell me your opinion and experience please. I made 317.000 km and catalisator is old 13 years...used last years very bad petrol that they sell here in Serbia country and last months Shell opened and i fill only VPSR V power super race 98 as they dont have 100 Octanes like in Austria Slovenia ect...
Last 2 years orange triangle lamp and engine pop out.
I reset with instrument and after long drive pop again.
Mechanic check also with Vida and say Catalysator...
Now tell me is maybe only O2 sensors front or rear to change or to buy new catalysator and sleep well?
Car on technical check for exhaust gases pass without problem not even near limits ect.
What you suggest? Thanks in advance for answers.
Here is photo and when i cancel also
ECM 400 C
p.s. dont worry about other as i have tuning software chip changed this work years well from 2013.
Other dtc i deleted and solved small oxidation on connectors.
