  1. XC60 (2010 - 2017)
    Happy New year to everyone. My 2011 XC60 T6 with 150K miles threw a P0420 code, my hand OBII wouldn't clear the code so I hooked up VIDA and sure enough the ECM fault code "Catalyst System Efficiency Below threshold (bank 1)" was there. Funny enough I was not able to delete the code using VIDA...
