2006 BMW M3 CONVERTIBLE check engine

132Laws and regulations
OBD interface socketThe 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 emis-
sion control system for the vehicle"s
lifetime. The system monitors emission-
related components and systems for
deterioriation and malfunction.
An illuminated 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 center at the
earliest possible opportunity.
Display in Canadian models for
the malfunction described
above.
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
seriously damage emission control
components, especially the catalytic
converter.
When the fuel filler cap is not
properly tightened, the OBD sys-
tem can detect the vapor leak and the
indicator will light up. If the filler cap is
subsequently tightened, the indicator
should go out within a few days.<
Event data recordersYour vehicle may be equipped with one
or more sensing and diagnostic mod-
ules or a recording device capable of
recording or transmitting certain vehicle
data or information. In addition, if you
have a Subscription Service Agreement
for the BMW Assist system, certain
vehicle information may be transmitted
or recorded in order to provide such
services.
