OBD interface socket

The interface socket for the Onboard
Diagnostic is located on the left of the
driver's side at the bottom of the instru-
ment panel and under a cover. The
cover has the letters OBD on it.

The purpose of the OBD system is to
ensure proper operation of the emis-
sion control system for the vehicle's
lifetime. The system monitors emission-
related components and systems for
deterioration and malfunction.

An illuminated lamp informs you
of the need for service, not of
the need to stop the vehicle.

However, the systems should be
checked by your BMW Sports Activity
Vehicle center at the earliest possible
opportunity.

Under certain conditions, the indicator
will blink or flash. This indicates a rather
severe level of engine misfire. When
this occurs, you should reduce speed
and consult the nearest BMW Sports
Activity Vehicle center as soon as pos-
sible. Severe engine misfire over only a
short period of time can seriously
damage emission control components,
especially the catalytic converter.

When the filler cap is not properly
tightened, the OBD system can

detect the vapor leak and the indicator
will light up. If the filler cap is subse-
quently tightened, the indicator should
go out within a few days.
