Is there a difference between the TDI catalytic converter and the catalytic converter on gasoline VW? The VW dealer list as two different parts, but the muffler dealer says they are the same. I was under the impression due to the different fuel the make up of the converter had to be different. I have been unable to find anyone that can tell me if the inside of the converter for the two different engines are the same or different. The problem happened when a friend had his converter replaced on his TDI and when it was at the dealer a few months later he was told that the new converter had already failed since it was designed for the gas VW.

No, they are totally different. If you put a Gas cat on there, it will fail just as it did for your friend. They gas cat and diesel cat are treating different things.
