Diagnosis frequency and MIL illumination: After refueling is detected, filler cap left open
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.
Description of chart:
This chart describes the diagnostic frequency for the case where refuelling is detected and the filler cap is left open. The filler cap diagnosis is done during the first driving cycle, as soon as the refuelling has been detected.
Because of the "check filler cap" message, the driver can fix the most common reason for system leaks. So the evaporative emissions are reduced compared to systems without "check filler cap" message.
To give the driver time for closing the filler cap without illuminating the MIL, the first "Leak supposed"-flag is ignored.
