engine BMW X5M 2012 Workshop Manual

Fuel
Fuel specifications
Gasoline engine: required fuel
Do
not use fuels that are labeled at the fuel pump
as containing metals.
Only refuel with lead-free gasoline without
metal additives
Do not refuel with leaded gasoline or gasoline
with metal additives, e. g., manganese or iron;
otherwise, the catalytic converter and other
components will be permanently damaged.◀
Do not refuel with ethanol E85
Do not refuel with E85, i.e., fuel with an
ethanol content of 85 %, or with Flex Fuel, as this
would damage the engine and fuel supply sys‐
tem.◀
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is:
▷ BMW X5: 87
▷ BMW X6: 89
If you use gasoline with this minimum AKI Rat‐
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no affect on the engine life.
Minimum fuel grade
Do not use any gasoline below the mini‐
mum specified fuel grade; otherwise, engine
damage may occur.◀
Use high-quality brands
Field

experience has indicated significant differ‐
ences in fuel quality: volatility, composition, ad‐
ditives, etc., among gasolines offered for sale in
the United States and Canada. Fuels containing
up to and including 10% ethanol or other oxy‐
genates with up to 2.8% oxygen by weight, that
is, 15% MTBE or 3% methanol plus an equiva‐ lent amount of co-solvent, will not void the ap‐
plicable warranties with respect to defects in
materials or workmanship.
Minimum fuel grade
The

use of poor-quality fuels may result in
driveability, starting and stalling problems es‐
pecially under certain environmental conditions
such as high ambient temperature and high al‐
titude.
Should you encounter driveability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may result in unscheduled maintenance.◀
BMW X5 with BMW Advanced Diesel:
required fuel
Ultra-Low Sulfur Diesel
The engine of your BMW is designed for diesel
with a low sulfur content:
Ultra-low sulfur diesel ASTM D 975-07a.
Only refuel with ultra-low sulfur diesel.
The percentage of biodiesel in the fuel
must not exceed 5%, referred to as B5. Do not
refuel with gasoline. If the vehicle has been re‐
fueled with incorrect fuel such as gasoline, do
not start the engine; otherwise, there is a danger
of engine damage.◀
If you added the wrong fuel, contact the service
center.
The fuel filling neck is designed for refueling with
diesel nozzles.
If the nozzle cannot be inserted into the fuel filler
pipe of your BMW, please check to make sure
that you are refueling with a diesel fuel pump and
whether this is equipped with a diesel nozzle. Seite 248
248 Online Edition for Part no. 01 40 2 606 735 - 03 11 500Fuel

In the event the Ultra-Low Sulfur Diesel fuel can‐
not be fully inserted into the fuel filler neck,
please contact BMW Roadside Assistance for
instructions on how to add fuel. For more infor‐
mation on BMW Roadside Assistance, refer to
page
281.
Winter diesel
To ensure that the diesel engine remains op‐
erational in the winter, use winter diesel.
It is available at gas stations during winter
months.
The standard fuel filter heating prevents the
supply of fuel from stalling during driving. No diesel additives
Do not add additives, including gasoline;
otherwise, engine damage may occur.◀ BMW X5 with BMW Advanced
Diesel
The concept
BMW
Advanced Diesel reduces nitrogen oxides
in the diesel exhaust of your vehicle by injecting
the reducing agent diesel exhaust fluid into the
exhaust line. In the catalytic converter, a chem‐
ical reaction occurs that minimizes nitrogen ox‐
ides.
In order to be able to start the engine in the usual
way, there must be a sufficient supply of diesel
exhaust fluid in the separate reservoir.
System heating
In order to bring the system to operating tem‐
perature after a cold start of the engine, the au‐ tomatic transmission shifts into the next higher
gear at a later point.
Reserve display
A display in the instrument panel informs you
about the remaining distance can be covered
with the amount of fuel currently in the tank.
The reserve display appears approx.
1,000 miles/1,600 km before the tank is empty.
As soon as the reserve display has appeared in
the instrument panel, have the diesel exhaust
fluid refilled to prevent the engine from being
unable to restart.
Diesel exhaust fluid at minimum
Even with a display of -- mls, the engine will con‐
tinue to run, provided that it is not switched off,
and all other operating requirements are met,
e.g. sufficient fuel.
No engine start
Do

not drive until the displayed remaining
distance runs out. Otherwise, it may not be pos‐
sible to restart the engine.◀ Seite 249

Incorrect fueling
The warning lamp lights up:
The reservoir has been filled with an in‐
correct fluid.
Please contact your service center.
Have diesel exhaust fluid refilled
This
exhaust fluid is refilled by your service cen‐
ter during regular maintenance. If you adhere to
this maintenance schedule, it is usually not nec‐
essary to refill any fluids between the mainte‐
nance dates.
Under certain circumstances, for example, due
to a particularly sporty driving style or operation
of the vehicle at high altitudes, it may be neces‐
sary to refill fluids between maintenance dates.
As soon as the reserve display has appeared in
the instrument panel, have the diesel exhaust
fluid refilled to prevent the engine from being
unable to restart.
You can have the fluid refilled by a service cen‐
ter.
Diesel exhaust fluid at low
temperatures
Due to its physical properties, it may be neces‐
sary to replenish the level of diesel exhaust fluid
at temperatures below +23 ℉/ -5 ℃, even be‐
tween the regular maintenance dates.
If the fluid needs to be refilled, this will be indi‐
cated with the reserve display in the instrument
cluster, refer to page 249.
Only refill the diesel exhaust fluid
yourself in exceptional circumstances
To be able to reach the nearest service center
with your vehicle, you may refill the diesel ex‐
haust fluid yourself, making sure to heed the
warning notices specified below. Handling diesel exhaust fluid
Do not allow diesel exhaust fluid to come
into contact with you. This can lead to skin and
eye irritation. Wear protective goggles and
gloves as needed. Follow the safety instructions
on the bottle. When opening the bottle or res‐ ervoir, pungent smelling vapors can escape. Be‐
fore refilling, close the vehicle completely so
that
the vapors do not get into the interior of the
vehicle. When handling diesel exhaust fluid in
enclosed spaces, make sure to have sufficient
ventilation. After handling diesel exhaust fluid,
wash hands thoroughly. Failure to do so may
lead to irritation, for instance, due to inadvertent
contact with the eyes. If eye irritation occurs,
immediately rinse eyes with ample water and
contact a doctor if necessary. If diesel exhaust
fluid comes into contact with surfaces of your
vehicle, rinse the affected surfaces with water or
else damage may occur. Keep diesel exhaust
fluid out of reach of children.◀
Suitable diesel exhaust fluid
▷ Preferred: BMW Diesel Exhaust Fluid. This
bottle and its special adapter permit con‐
venient refilling with diesel exhaust fluid.
▷ Alternative: NOx reduction agent AUS 32
Diesel exhaust fluid can be obtained from your
service center.
