Advanced Diesel
The concept
BMW Advanced Diesel reduces nitrogen ox‐
ides in the diesel exhaust of your vehicle by in‐
jecting the reducing agent diesel exhaust fluid
into the exhaust line. In the catalytic converter,
a chemical reaction occurs that minimizes ni‐
trogen oxides.
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.
