2017 BMW X3 check engine

CAUTION
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 Top Tier retailers.
Failure to comply with these recommendations
may result in the need for unscheduled main‐
tenance.◀
Recommended fuel grade
BMW recommends AKI 91.
Minimum fuel grade
BMW recommends AKI 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 effect on the engine life.

Information ATTENTION
Do not press the Start/Stop button after
refueling with the wrong fuel. There is a risk of
damage to property.
Observe the following for diesel engines:▷Use only Ultra-Low Sulfur Diesel. Maxi‐
mum content of biodiesel: 5 %, B5.▷Do not use rapeseed methyl ester RME.▷Do not use biodiesel above 5 %, B5.▷Do not use gasoline.▷No diesel additives.Do not press the Start/Stop button after refuel‐
ing with the wrong fuel. Contact a dealer’s
service center or another qualified service cen‐
ter or repair shop.◀
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 gas‐
oline. If you do fill the tank with the wrong fuel,
e.g., gasoline, do not start the engine as this
may damage the engine.
In the case of incorrect refueling, contact a
dealer’s service center or another qualified
service center or repair shop or Roadside As‐
sistance.
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.

BMW Advanced Diesel
The concept BMW Advanced Diesel reduces nitrogen ox‐
ides in the diesel emissions by injecting diesel
exhaust fluid into the exhaust system. A chem‐
ical reaction takes place inside the catalytic
converter that minimizes nitrogen oxides.
The vehicle has a tank system that can be refil‐
led.
To be able to start the engine as usual, there
must be an adequate diesel exhaust fluid.
Warming up the system
In order to warm the engine up to its operating
temperature after a cold start, the Steptronic
transmission may subsequently shift up to the
next higher gear.
Displays in the instrument cluster
Reserve indication This display in the instrument cluster provides
information about the distance that can still be
driven with the current reserve level.
Do not continue driving to the limit of the re‐
maining travel distance. It is not possible to re‐
start the engine after switching it off.▷Lamp white: refill with diesel
exhaust fluid at the next op‐
portunity.▷Lamp yellow: not enough
diesel exhaust fluid present.
The remaining range is dis‐
played in the instrument
cluster. Immediately refill
with diesel exhaust fluid.
Diesel exhaust fluid on minimum
▷The remaining range is dis‐
played in the instrument
cluster: add diesel exhaust
fluid. The engine will con‐
tinue to run as long as it isnot switched off and all
other operating conditions
are satisfied; sufficient fuel,
for example.
System malfunction
A Check Control message is displayed when
there is a system not working.
Have the diesel exhaust fluid
replenished
BMW recommends that diesel exhaust fluid be
added by the dealer’s service center within the
course of regular maintenance.
In addition it may be necessary to have the
fluid replenished several times under particular
circumstances, for example, if the vehicle is
driven in a particularly sporty style or if it is
driven at high altitudes.
The diesel exhaust fluid must be replenished
as soon as the reserve display appears in the
instrument cluster to avoid not being able to
restart the engine.
Diesel exhaust fluid at low
temperatures
Due to its physical properties, it is possible
that the diesel exhaust fluid may also need to
be replenished between regular maintenance
appointments if it is exposed to temperatures
under + 23 ℉/- 5 ℃. In this case, add diesel ex‐
haust fluid only immediately before driving off.
At temperatures below + 12 ℉/- 11 ℃, the fill‐
ing level cannot be measured in some cases.
Replenishing diesel exhaust fluid
yourself in exceptional cases
General information You can replenish diesel exhaust fluid yourself
in exceptional cases, for example, to get to
your scheduled service.
