I replaced my cats because of the 02 code, drove out of the mechanics and not 10mins later the code came up again, not happy, cost a fortune after already having them cleaned before replacing them. I have a 2010 VE SSV6 ute
I have replaced the catalytic convertors but the engine light still comes on saying they are both not working efficiently.
Is there a reset that needs to be done? They are after market Cats but supplier says he's never had a problem, I feel like surely both cats can't be faulty? Is it an issue...
