I have a 99' 528i and recently the check engine light has come on. I haven't
had a chance to get it to a shop yet, but reading in the manual it says this
light is for emissions only. Will there be any harm to the car if I drive
with this light on for abit till I can get into the shop? My guess is that
it might be O2's as the car has 183K mi on the clock and im not sure when
they were replaced, but again this is my guess.

Thank you,

It means you need to get the OBD2 code read to determine what the
problem is. You may be right about the O2 sensor, but you also may be
wrong. Considering the O2 sensors cost about $100 I'd spring for a
diagnosis before throwing parts at it. But that's just me... ;-)
