P0420 and 0430
My 2007 x5 3.0 with 115k miles is throwing the P0420 and 430 codes. I have attached the report from Torque, and it shows the catalyst Monitors to be above max. When I real time monitor in OBD Fusion there is no voltage showing for oxygen sensor 1 but not sure which bank that is. I am going to put spacers in the rear sensors to see if that solves it. Unfortunately I have to get a smog check ASAP.

PO420 and PO430
Did you resolve your PO420 and PO430 codes? I'm having the same problem and have spent months trying determine a solution.

Probably a bad 02 sensor. They are hit or miss after 100k miles.

+1 Oxygen sensors are considered a wear item and should be replaced every 100,000 miles.
