OBD Socket
The Onboard Diagnostics OBD interface
socket is located on the left of the driver's side
under the instrument 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 emission control sys-
tem for the vehicle's lifetime. The system mon-
itors emission-related components and sys-
tems for deterioration and malfunction.
An illuminated indicator 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 cen-
ter at the earliest possible opportunity.
Display of the previously described
malfunction on Canadian models.
Under certain conditions, the indicator
lamp 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 seriously damage emissions control
components, especially the catalytic converter.
When the fuel filler cap is not properly
tightened, the OBD system can detect
the vapor leak and the indicator lamp will light
up. If the filler cap is subsequently tightened,
the indicator lamp should go out within a few
days.<
Event Data Recorders
Your vehicle may be equipped with one or more
sensing and diagnostic modules or a recording
device capable of recording or transmitting cer-
tain vehicle data or information. In addition, if
you have a Subscription Service Agreement for
the BMW Assist system, certain vehicle infor-
mation may be transmitted or recorded in order
to provide such services.
Care
Important information on care and maintenance
of your BMW is contained in the Caring for your
vehicle brochure.
