I would love to know what came of this as well. I have a 2011 xc90. Engine light came on. OBD2 code was P0420. Mechanic quoted me 5K to replace catalytic converter. I said no way! Talked to another mechanic. He gave me BG44K fuel additive. Drove about 200+ miles. I followed that up with Cataclean. After filling up, engine light came on 2 days later. Same code, P0420. Ive read so many of these posts, and it seems like people go down a rabbit hole of replacing parts and still unable to fix the problem. Has anyone been able to find a fix for this? All of these message boards just drop off without any solutions that actually work.
