Shop found codes P0431 & P1131 for bank 2 O2 sensor circuits and recommended replacing bank 2 cat converter and both sensors for a mere $2300. Dang California doesn't allow sale of aftermarket cat converters for the A6. I think I'll go to NV and buy a universal fit or have a buddy in another state mail it to me. Anyone have any experience with this issue and cost?
