Diagnostic Overview

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.

When the engine is in a stable idle condition, the purge valves are opened and closed. The deviation of some engine parameters is the sign for a mass flow through the valve.
