replace the O2 sensors and the light should go off, unless you need new cats. and yes you should replace the O2 sensors if there is a fault for them. if they weren't a big deal and didn't matter if they were replaced or not then why would BMW make it so if the DO fail a light comes on for it.

You can reset and clear the code with an OBDII unit, but since the problem is recurring it will just return if you don't fix the problem. If the O2 sensors are bad you should replace them.

You can buy a fault code reader and reset tool. Try reseting the it and see if it goes away. If if does i guess you are fine, however if it doesn't it is advisable that you replace the faulty part.

Check the link below for some fault code readers and reset tools
