Hello, I have a 2003 Audi A4 1.8T, Automatic, Frontrak
Since I have owned the car, the catalytic converter has been changed 3 times since Jan '12
I drive the car for awhile, and get the pesky code: 0420.
Changed the o2 sensors as well. I have been getting them changed with after markets cats.
I was told that after-market and Audi dont mix.
Now, I have no choice but to buy the original OEM cat converter that's over $1000 at the dealer.
However, just wondering, Audi too gets their parts from another source, so who makes their cats??
I want to save some money and buy directly from the main company that Audi sub contracts.
