Overview

OBD interface socket

The OBD interface socket for onboard
diagnostics is located on the driver's
side at the left-hand bottom of the in-
strument panel and under a cover. The
cover has the letters "OBD" on it.

The purpose of the OBD system is to
assure proper emission control system
operation for the vehicle's lifetime by
monitoring emission-related compo-
nents and systems for deterioration and
malfunction.

An illuminated indicator informs you of
the need for service, not that you need
to stop the vehicle. Your system should
be checked, however, at the earliest
possible opportunity.

If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact your near-
est BMW center immediately. Severe
engine misfire over even a short period
of time can seriously damage emission
control components, especially the cat-
alytic converter.

If the fuel filler cap is not on tight
enough, the OBD system can detect
leaking vapor and the indicator will light
up. If the fuel filler cap is then tightened,
the indicator will usually go out after a
short period of time.
