100,000 mile service

[J to the O]

I have a E39 BMW 528i 1998 and I was wondering what needs to be done at 100,000 mile service. Do the O2 sensors need to be replaced? Any information would be great!!!

Thanks

O2 sensors are expected to go at about 100k miles
but I wouldn't replace them until you actually get the lights on your dash,
or you experience some rough idling and poor gas consumption.

Cosmos is right.

Personally, I would replace the O2 sensors becuase i'm picky about stuff running right no matter what, BUT the O2 sensors for your car are very expensive, so if you dont want to spend the $$ right now, just wait for the check engine light to come on.
