Socket for Onboard

Diagnosis OBD

On the driver's side is an OBD socket for check-
ing components relevant to the composition of
the vehicle's emissions.

Emissions

The warning lamp lights up:
The vehicle is producing higher emis-
sions. The trip can be continued. Have

the car checked as soon as possible.

Canadian models display this warning
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. Make sure that the gas cap is cor-
rectly positioned and close it until it audibly
clicks.

Data memory

Your vehicle records data about the operation,
faults, and user settings. These data are stored
in the vehicle and in extract form, in the remote
control, and can be read out using suitable
devices at your BMW center. The data that are
read out are used to support service proce-
dures and repairs or to optimize and expand
vehicle functions. If you have a BMW Assist
contract, certain vehicle data can also be trans-
mitted directly from the vehicle in order to
enable the desired services.
