CEL - Code P0432
I have a '99 A6 Avant with 116,000 miles on it that is throwing this code:
16816 - P0432 - Main Catalyst,Bank2 Efficiency Below Threshold
This first came up about three weeks ago so I had the bank 2 (driver's side) Catalytic Converter replaced, but yesterday the CEL came on and it is throwing the same code again.
This is the only code I get, and it runs well. Has anyone else experienced this? Would the O2 sensors need replacing without any sensor codes being thrown?

Step one for me would be to swap the bank 1 and 2 oxygen sensors.
I would do that before changing the cat. Shops like to change cats because not only do they make money on the new cat, but the cores are worth money too.
