2006 C55 catalytic converter
Hello everyone,
I am having trouble passing emissions on my 2006 C55. The check engine light is on with codes P0151 and P0174. I am also suspect that the catalytic converter is cracked itself but there are no OEM parts available to replace it let alone finding a used one.
Has anyone dealt with similar issues? Any recommendations on good aftermarket cats or tips for passing emissions?
I am testing in Illinois.
Thank you.
