Description of leak check

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2010 BMW M6, 2010 BMW M5, 2009 BMW M6, 2009 BMW M5, and 2008 BMW M6. However, it is still accessible from the selected car via links, so may be relevant.

The leak check operates very similar to the minimum air flow check with the only difference, that a leak is detected in case the flow exceeds the secondary airflow model considerably. The bank allocation is identical.
