Maintenance

OBD interface socket

The Onboard Diagnostic 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 monitors emission-related compo-
nents and systems for deterioration and mal-
function.

If the Service engine soon indicator
lamp comes on either continuously or
intermittently, this indicates a fault in

the emission-related electronic systems.
Although the vehicle remains operational, you
should have the systems checked by your
BMW center at the earliest possible opportu-
nity.

The illuminated indicator informs you of the
need for service, not that you need to stop the
vehicle. However, the systems should be
checked by your BMW center at the next oppor-
tunity.
If the indicator blinks or flashes, this indicates a
high level of engine misfire. Reduce speed and
contact the nearest BMW center immediately.
Severe engine misfiring over even a short
period of time can seriously damage emission
control system components, especially the cat-
alytic converter.

Indication of the above-described mal-
function in Canadian models.

If the gas cap is not on tight enough, the
OBD system can detect leaking vapor

and the indicator will light up. If the gas cap is
then tightened, the indicator will usually go out
after a short period of time.

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.
