OBD connector
The Onboard Diagnostic (OBD) connec-
tor is located on the left of the driver's
side at the bottom of the instrument
panel and under a cover (arrow).
The cover has the letters "OBD" on it.
The purpose of the OBD system is to
ensure proper emission control system
operation for the vehicle's lifetime by
monitoring emission-related compo-
nents and systems for deterioration and
malfunction.

An illuminated Service Engine
lamp informs you of the need for
service, not of the need to stop
the vehicle. However, the sys-
tems should be checked by your
BMW center at the earliest pos-
sible 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.<
