I just bought a 2017 Lincoln Continental 3.7 l v6 used 90k from a Volkswagen dealership it was a trade in and I only had the car for just little over a month I got a code p0430 the next day after buying it and I’ve taken it back to the dealership as they wanted to make things right they did a cataclean for the fuel injectors it cleared the light for a couple of days then it came on again I took it back the following week and they did a tune up a week later today the engine light came on again with the same p0430 code for the catalyst system I’m starting to think I bought a bad car but it runs normal with no issues any advice?
Please see our FAQ
any advice?
Did you troubleshoot the various items that can trigger the P0420/P0430 code aside from the catalytic converter? (Both codes refer to the same fault but in different banks.)
