    Hi guys!

    So both p0420 and p0430 codes showed up at the exact same time. Took it to the dealer and had it fully tested and they say it's both cats that have failed. I find it very hard to believe that both cats would go the same time, so before I spend the money I want to ask if anyone might know of another reason that may cause these codes.

    Thanks
