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 conditions. 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 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.
