Components which are decisive for the

the OBD socket with a device.
This socket is located on the driver's side on the

Exhaust-gas values
The warning lamp lights up:
The vehicle emissions are raised. The
trip can be continued. Have the vehicle
checked as soon as possible.
Display of the previously described
malfunction in Canadian models.
The lamp flashes under certain condi-
tions. This is a sign of excessive misfiring of the
engine. In this case you should reduce speed
and drive to the nearest BMW center as soon as
possible. Heavy engine misfiring causes seri-
ous damage to the emission-relevant compo-
nents, especially the catalytic converter, within
a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system will assume that
fuel vapor escapes. Then a display lights up. If
the cap is then tightened, the display will go out
within a few days.
