2012 BMW 640I COUPE engine

Socket for OBD Onboard
Diagnosis
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.
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
Assist, certain vehicle data can be sent directly
from the vehicle to facilitate the desired serv‐
ices.Seite 261MaintenanceMobility261

Vehicle care
Car care products
BMW recommends using cleaning and care
products from BMW, since these have been
tested and approved.
Car care and cleaning products
Follow the instructions on the container.
When cleaning the interior, open the doors or
windows.
Only use products intended for cleaning vehi‐
cles.
Cleansers can contain substances that are dan‐
gerous and harmful to your health.◀
Vehicle paint
Regular care contributes to driving safety and
value retention.
Environmental influences can act on the vehicle
paint. Tailor the frequency and extent of your car
care to these influences.
Leather care
Remove dust from the leather often, using a
cloth or vacuum cleaner.
Otherwise, particles of dust and road grime
chafe in pores and folds, and lead to increased
wear and premature degradation of the leather
surface.
To guard against discoloration, such as from
clothing, provide leather care roughly every two
months.
Clean light-colored leather more frequently be‐
cause soiling on such surfaces is substantially
more visible.
Use leather care products; otherwise, dirt and
grease will gradually break down the protective
layer of the leather surface.
Suitable care products are available from the
service center.Seite 274MobilityCare274
