2006 BMW M3 COUPE check engine light

128Laws and regulations
OBD interface socketThe Onboard Diagnostic (OBD) inter-
face 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.

The indicator lamp above the buttons
lights up. As soon as a telephone con-
nection has been set up with the Mobile
Service, the indicator lamp flashes.
Depending on the country you are in,
your vehicle's current location will also
be transmitted if your vehicle is
equipped with an activated BMW Assist
function.
Jump-startingWhen your battery is discharged, you
can use two jumper cables to start your
vehicle with power from the battery in a
second vehicle. You can also use the
same method to help start another
vehicle. Use only jumper cables with
fully insulated handles on the terminal
clamps.
Do not touch high-voltage wiring
and cables on a running engine.
Contact with components carrying high
voltage can be harmful or fatal.
Carefully observe the following instruc-
tions to avoid personal injury and/or
damage to one or both vehicles. support vehicle has 12 volts and
approximately the same capacity –
measured in Ah. This information is
provided on the battery
2. Stop the engine of the support vehi-
cle
3. Switch off all consumers in both
vehicles.
Make absolutely certain that there
is no contact between the body-
work of the two vehicles, otherwise
there is a short circuit hazard.<
Connecting the jumper cables
Be sure to connect the jumper
cables in the right order; other-
wise there is a risk of injury due to
sparks being created near the battery.<
The jump-starting terminal located in
your BMW's engine compartment
serves as the positive battery terminal;
refer also to the engine compartment
overview on page 120. The cover of this
auxiliary terminal is marked with a +.

starting terminal. Do so by pulling the
tab – see arrow 1

plus/+ jumper cable to the positive
