Socket for OBD Onboard

Diagnostics interface

Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located to the left on the driver's
side, on the underside of the instrument panel
under a cover.

Exhaust-gas values

The warning lamp lights up. The
exhaust-gas values worsen. 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.

Event Data Recorders

Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with
a device for recording or transmitting certain
vehicle data or information. If you have also sub-
scribed to BMW Assist, certain vehicle data can

be transmitted or recorded to enable corre-
sponding services.
