P0420 and p0430 codes appear despite full catalyst change.

Customer Question
P0420 and p0430 codes...

P0420 and p0430 codes appear despite full catalyst change

Mechanic's Assistant: Just to clarify, what's the exact code? And have you tried to reset it?

Its the 2009 Touareg 3.6. yes it was reset but keeps appearing after 100-200km

Mechanic's Assistant: Are you fixing your Touareg yourself? What have you tried so far?

No - it was over at my VW shop over here in Poland and they claimed that the catalysts were gone after 126000miles so I had them changed and the engine check sign appeared again

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Ok thanks
