catalytic converter BMW 320I XDRIVE 2014 Owners Manual

FuelVehicle equipmentAll standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Fuel recommendation Note General fuel quality
Even fuels that conform to the specifica‐
tions can be of low quality. This may cause en‐
gine problems, for instance poor engine start‐
ing behavior, poor handling and/or
performance. Switch gas stations or use a
brand name fuel with a higher octane rating.◀
Gasoline
For the best fuel economy, the gasoline should
be sulfur-free or very low in sulfur content.
Fuels that are marked on the gas pump as con‐
taining metal must not be used.
Refuel only with unleaded gasoline with‐
out metallic additives.
Do not refuel with any leaded gasoline or gaso‐
line with metallic additives, e. g. manganese or
iron, or permanent damage to the catalytic
converter and other components.◀
Fuels with a maximum ethanol content of
10 %, i. e., E10, may be used for refueling.
Ethanol should satisfy the following quality
standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xxxx: comply with the current standard in each
case.
Do not use a fuel with a higher percent‐
age of ethanol
Do not use a fuel with a higher ethanol per‐
centage than recommended or one with other
types of alcohol, i.e. no Flex Fuel, otherwise
this could damage the engine and fuel supply
system.◀
Recommended fuel grade BMW recommends AKI 91.
Minimum fuel grade
BMW recommends AKI 89.
Minimum fuel grade
Do not use any gasoline below the mini‐
mum fuel grade as this may impair engine per‐
formance.◀
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 effect on the engine life.
Fuel quality
The use of poor-quality fuels may result
in harmful engine deposits or damage. Addi‐
tionally, problems relating to drivability, start‐
ing and stalling, especially under certain envi‐
ronmental conditions such as high ambient
temperature and high altitude, may occur.
If drivability problems are encountered, we rec‐
ommend switching to a high quality gasoline
brand and a higher octane grade — AKI num‐
ber — for a few tank fills. To avoid harmful en‐
gine deposits, it is highly recommended to
purchase gasoline from BP or Top Tier retail‐
ers.Seite 180MobilityFuel180

Failure to comply with these recommendations
may result in the need for unscheduled main‐
tenance.◀
Diesel
Low-Sulfur Diesel
The engine of your BMW is designed for diesel
with low sulfur content:
Ultra-Low Sulfur Diesel ASTM D 975-xx.
xx: comply with the current standard in each
case.
Use only Ultra-Low Sulfur Diesel.
The fraction of biodiesel in the fuel must
not exceed 5 %, referred to as B5. Do not use
gasoline. If you do fill the tank with the wrong
fuel, e.g., gasoline, do not start the engine as
this may damage the engine.◀
After adding the wrong fuel, contact your serv‐
ice center or roadside assistance.
If the fuel pump nozzle does not fit in the filler
pipe of your BMW, please check to ensure that you are refueling at a diesel fuel pump that is
equipped with a diesel fuel pump nozzle.
In the event the Ultra-Low Sulfur Diesel fuel
cannot 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 216.
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 fuel filter heating system, included as a
standard feature, prevents disruption of the
fuel supply while driving.
Do not add any diesel additives
Do not add additives, including gasoline;
otherwise, engine damage may occur.◀
BMW Advanced Diesel
The concept BMW Advanced Diesel reduces nitrogen ox‐
ides in the diesel emissions by injecting diesel
exhaust fluid reducing agent into the exhaust
system. A chemical reaction takes place inside
the catalytic converter that minimizes nitrogen
oxides.
The vehicle has a tank that can be refilled.
To be able to start the engine as usual, there
must be an adequate reducing agent.
Reducing agent is added by the service center.
Warming up the systemIn order to warm the engine up to its operating
temperature after a cold start, the automatic
transmission may subsequently shift up to the
next higher gear.
Displays in the instrument cluster
Reserve display
This display in the instrument cluster provides
information about the distance that can still be
driven with the current reserve level.
The reserve display is shown
starting at a remaining range of
approx. 1,000 miles/1,600 km.

correspondingly trained personnel and other
authorized persons. Otherwise, use may result
in operating problems for the vehicle.◀
Position
There is an OBD socket on the driver's side for
checking the primary components in the vehi‐
cle emissions.
Emissions
▷The warning lamp lights up:
Emissions are deteriorating. Have
the vehicle checked as soon as
possible.
Canadian model: warning light indi‐
cates the engine symbol.▷The warning lamp flashes under certain
circumstances:
This indicates that there is excessive mis‐
firing in the engine.
Reduce the vehicle speed and have the
system checked immediately; otherwise,
serious engine misfiring within a brief pe‐
riod can seriously damage emission con‐
trol components, in particular the catalytic
converter.Seite 203MaintenanceMobility203
