MOBILITY
BMW Diesel with
BluePerformance
Principle
BMW Diesel with BluePerformance reduces ni-
trogen oxides in the diesel exhaust by injecting
the reducing agent AdBlue into the exhaust
pipe system. In the catalytic converter, this
produces a chemical reaction that reduces ni-
trogen oxides to a minimum.
General
The vehicle has a tank which requires topping
up.
There must be a sufficient amount of the re-
ducing agent present in order for drive-ready
state to be activated the usual way.
The reducing agent can be topped up at any
time.
The reducing agent AdBlue is a registered
trademark of the Verband der Automobilindus-
trie e. V. (VDA).
The reducing agent is available at many serv-
ice stations.
Preferably top up with reducing agent at a
pump dispenser.

If the filling level is too low, a Check Control
message is displayed.
Displays in the instrument cluster
Fuel reserve indicator light
The fuel reserve indicator light in the instru-
ment cluster notifies you if the reducing agent
fill level in the tank is low.
Do not allow the reducing agent tank to run
completely empty, as otherwise it will not be
possible to switch drive-ready state back on
after stopping the engine.
A yellow warning light is illumi-
nated in the instrument cluster:
filling level too low. The remain-
ing range is shown in the instru-
ment cluster. Top up with at
least 5 litres, 1.3 gal of reducing
agent immediately.
AdBlue on the minimum level
The reducing agent tank is
empty. Immediately top up with
at least 15 litres, 4 gal of reduc-
ing agent. The engine will con-
tinue to run provided that it is
not stopped and all other oper-
ating conditions are met, for example, there is
sufficient fuel.
System fault
If there is a system fault, a Check Control mes-
sage is displayed.
Visit the nearest Service Partner of the manu-
facturer or another qualified Service Partner or
a specialist workshop.
Having AdBlue topped up
BMW recommends having the reducing agent
topped up by a Service Partner as part of a
regular maintenance schedule.
