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 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.
