OBD connector

The interface socket for the onboard di-
agnosis system is located beneath a
cover on the center console front panel
(arrow).

A sticker with the text "OBD" is at-
tached to the cover.

The purpose of the OBD (Onboard
Diagnostic) system is to assure proper
emission control system operation for
the vehicle’s lifetime by monitoring
emission-related components and
systems for deterioration and malfunc-
tion.

An Illuminated indicator informs
you of the need for service, not
of the need to stop the vehicle.

However, the systems should be
checked by your BMW 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 center as
soon as possible. Severe engine misfire
over only a short period of time can se-
riously damage emission control com-
ponents, especially the catalytic con-
verter.

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
extinguish within a few days.
