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.
