and now re-reading your previous thread about putting diesel in the car, it's quite likely that the code is just a temporary one as the sensors didn't like the way the diesel fumes interacted with them. But, there's also a possibility that your catalytic converters are damaged, so taking it to the dealer is still the best bet.
