WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.
An incorrectly installed mixer cannot distribute the dosed AdBlue in the exhaust pipe properly so that a complete conversion of nitrogen oxide can occur. The conversion of the nitrogen oxide is monitored by the nitrogen oxide sensors. Entries are made in the corresponding fault memories,
Check whether the retaining claws of the mixer are facing away from the direction of travel. Observe repair instructions.
NOTE:
After replacing the mixer, the adaptations of the exhaust emission system must be deleted.
