The car takes a while before it goes into sleep mode, so you will hear various devices until it shuts off, But ! as I said it waits for any opportunity to stay awake, which is why leaving certain things plugged into the aux socket etc the car thinks it needs to stay out of sleep mode!!!! Sleep mode is also a timed interval before it engages which is why when some of the guys just leave the top down and the doors unlocked don't have an issue!!!! One has to remember some systems are on!!! all the time like the anti-theft etc..
Always said I would go back to a 6 series
