Hello From Myrtle Beach SC

[Eldlwms3]

I Drive a 2000 528i, and my check engine light came on. I checked the codes and found that the O2 sensor may be bad, so I replaced them all. Engine light when out for a while, but it recently came back on with different codes, but still having to do with the O2 sensors. Anybody else having that problem?
