Socket for OBD Onboard
Diagnostics interface
A diagnostics device can use the OBD socket to
check components critical to exhaust composi-
tion.
This socket is located under a cover on the left
side of the driver's footwell, directly under the
dashboard.
Exhaust-gas values
The warning lamp lights up. The
exhaust-gas values are deteriorating.
Have the vehicle checked as soon as
possible.
Display of the previously described
malfunction on Canadian models.
The lamp flashes under certain conditions. 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 serious damage
to the emission-relevant components, espe-
cially the catalytic converter, within a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system can detect the
escape of fuel vapor. This causes a display to
light up. If the cap is then tightened, the display
should go out within a few days.
