Hi, how can I change the O2 sensor and the catalytic converter and after that how can I tell there is no further problem that I need to work on. Thanks

STOP RIGHT THERE. DO NOT CHANGE ANYTHING EMISSIONS RELATED AT 75K, the federal warranty still applies and BMW is going to fix it for you, unless you f***** it up somehow.
