Socket for On-Board

Diagnosis OBD

Primary components that make up exhaust
emissions can be checked by a device via the
OBD socket.
This socket is located on the driver's side to the
left, on the bottom of the instrument panel
underneath a cover.

Exhaust emission values

The warning lamps come on. The
exhaust emission values have wors-
ened. Have the car checked as soon
as possible.
Canadian models display these warn-
ing lamps.

The lamps flash under certain condi-

tions. This indicates excessive misfiring in the
engine. If this happens, you should reduce your
speed and visit your nearest BMW Center as
soon as possible. Severe engine misfiring can
quickly lead to serious damage of emissions-
related components, especially the catalytic
converter.
If the gas cap is not properly tightened, the OBD
system will assume that fuel vapor is escaping.
An indicator will then light up. If the gas cap is
then tightened, the indicator will go out within a
few days.

Event data recorders

Your vehicle may be equipped with one or sev-
eral measuring or diagnostic modules or a
device for recording or sending certain vehicle

data or information. In addition, if you have
signed a subscription contract for BMW Assist,
certain vehicle data may be transmitted or
recorded in order to facilitate the corresponding
services.

Care

Important information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.
