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 chemical reaction occurs that minimizes nitrogen 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 temperature after a cold start of the engine, the automatic automatic transmission shifts into the next higher gear at a later point.
