Fellow D2 drivers, I've recently been clearing the P0420 code, and they keep returning., It's a bank 1 fault. For some reason, the right cat is very expensive compared to the left one...I need the right (Audi 4D0-254-550-BX). This part costs around 1,400 - 1,500. I'd like to source an OEM equivalent or perhaps get a break for a dusty one sitting in a warehouse. Low mileage (on the cat) from parts cars OK too.
Thanks for any replies here, or call, text me on 703-283-6100 or email at email@example.com
