    there are 2 but whoa!!! before you buy cats get your eng module part number. if its one of these 3B0 907 551 G, 3B0 997 552 GX, 3B0 907 551 AS or 3B0 997 551 X then there is a reprogram flash to correct codes for catalyst low efficiency. an audi dealer can perform the flash for under 2 hours. i would start with this unless cat damage is obvious.
