Fault code P0430......Advise please!!!!!
ok one for the techies out there........I've got an engine fault light come up on the dash of my 996 GT3 RS so I've run a diagnostic check and it's code P0430 which is 'cat running below threshold on bank 2' (the right hand side bank of cylinders as you look into the engine bay) which I've been advised it's the post Cat oxygen sensor by a reputable Indie my question is why should it be the post Cat and not the Pre Cat sensor is it that there's a different code for Post Cat sensor ie; P0431, equally why is not the Cat again is there a different code ie: P0429......oh and just to let on the afore mentioned Indie chsnged the post cat sensor last week and this weekend the same fault code appeared as said so I'm a bit narked to say the least not only because of this but it cost me £425 
becuase they couldn't just take it out as it was corroded in apparently and they had to take the rear PU off and dismantle the exhaust so they could get the cat on the work bench etc etc.

If you erase this code and it continues to come back then you have to change catalytic converter.
The change of the 02 sensor that reads Volts to check efficiency rules out that the cause of problem is the sensor itself.
If the cat is not broken you can just ignore the light and keep driving.
Sometimes when it gets hotter maybe you won't see it at all.

If you do trackdays the cats get rattled apart after a while. Mine were toast but fortunately got 911Slows cargraphic 200 cell cats which are metal rather than ceramic (I believe) so should be more resistant.
