Socket for OBD Onboard
Diagnosis
Position
There is an OBD socket on the driver's side for
checking the primary components in the vehicle
emissions.
Emissions
▷ The warning lamp lights up:
Emissions are deteriorating. Have
the vehicle checked as soon as pos‐
sible.
Canadian model: warning light indi‐
cates the engine symbol.
▷ The warning lamp flashes under certain cir‐
cumstances:
This indicates that there is excessive misfir‐
ing in the engine.
Reduce the vehicle speed and have the sys‐
tem checked immediately; otherwise, seri‐
ous engine misfiring within a brief period can
seriously damage emission control compo‐
nents, in particular the catalytic converter.
Fuel cap
The indicator lamp lights up.
If the fuel cap is not properly tightened,
the OBD system may conclude that fuel
vapor is escaping. If the cap is then tightened,
the display should go out in a short time.

Maintenance
Data memory
Your vehicle records data relating to vehicle op‐
eration, faults and user settings. These data are
stored in the remote control and can be read out
with suitable devices, particularly when the ve‐
hicle is serviced. The data obtained in this way
provide valuable information for service proc‐
esses and repair or for optimizing and develop‐
ing vehicle functions further.
In addition, if you signed a service contract for
BMW Assist, certain vehicle data can be sent
directly from the vehicle to facilitate the desired
services.
Event Data Recorder EDR
This vehicle is equipped with an event data re‐
corder EDR. The main purpose of an EDR is to
record, in certain crash or near crash-like situa‐
tions, such as an air bag deployment or hitting a
road obstacle, data that will assist in under‐
standing how a vehicle's systems performed.
The EDR is designed to record data related to
vehicle dynamics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record
such data as:
▷ How various systems in your vehicle were
operating.
▷ Whether or not the driver and passenger
safety belts were fastened.
▷ How far, if at all, the driver was depressing
the accelerator and/or brake pedal.
▷ How fast the vehicle was traveling.
These data can help provide a better under‐
standing of the circumstances in which crashes
and injuries occur.
EDR data are recorded by your vehicle only if a
nontrivial crash situation occurs; no data are re‐
corded by the EDR under normal driving condi‐
tions and no personal data, e.g., name, gender,
age, and crash location, are recorded.
