Socket for Onboard

Diagnosis OBD

Primary components that make up exhaust
emissions can be checked by a device via the
OBD socket.
This socket is located under a cover on the left
on the driver's side.

Exhaust emission values

The warning lamp lights up:
The vehicle emissions are raised. The
trip can be continued. Have the car

checked as soon as possible.

Canadian models display this warn-
ing lamp.
The lamp flashes 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.

The warning lamp comes on if the gas
cap is not properly tightened and the
OBD system assumes that fuel vapor

is escaping. If the gas cap is then tightened, the
warning lamp should go out within a few days.

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 service contract for BMW Assist, cer-
tain vehicle data may be transmitted or
recorded in order to facilitate the corresponding
services.
