Question about 2004 BMW 3 Series
Replaced "Intake actuator" and no code but "O2 sensor" and "Evaporate System" not ready- how to fix? Thanks
Take the car to an AutoZone IF it's driveable, ask for the free check on "alarms" and they can set it up to reset.

Replace the Oxygen sensor. All your trouble codes are downstream of the oxygen sensor, and are related to it.
Once you replace the oxygen sensor (replace with a BOSCH sensor!), remove the positive battery cable, step on your brakes for 10 seconds, then reattach the cable. This will clear the codes from your ECM (Electronic Control Module).

if the 02 sensor is unplugged and you are reading a scan tool from the diagnostic link then of course the 02 reading is wrong
if you are using a volt meter right at the connector thats on the sensor then the 02 will read lean because the heating elements in it are disconnected when you unplug it
check 02 voltage with engine warmed up and 02 sensor connected you will have to pierce insulation with your probe
