If the front wheels are turned more than [x] degrees, AO won't engage. (I couldn't remember the number.)
If there is too much load on the engine (i.e., AC is at max), AO won't engage.
There were roughly 10-15 circumstances where AO wouldn't activate even if it was left "on".
I don't remember all of them, but there's probably something written more about these exceptions on one of BMW's websites.

Here is the list i have posted numerous times
Stop Start wont engage if :
a) Outside temperature is below 37F (3C)
b) Outside temperature is above 95F (35C)
c) Car interior has not yet cooled or warmd up
d) Engine not yet warmed up (does not have to reach full operating temp)
e) Battery charge low
f) Directly after car was driven in reverse
g) Stering wheel is turned after car has stoped
h) Stop and Go traffic
i) Gear selector in Sport or Manual
j) ABS was activated before stopping
k) Windshield is fogging up |
Okay, is anyone willing to jam one of the sensors? For example, what if take some translucent tape - a small piece, and place it over whatever sensor is used to determine there is mist on the windshield?
Next, you would have to disable the auto button on the driver's air condition since auto mode attempts to react and clear the mist.
This way, if the system always thought there was mist on the windshield then it will never enable start stop?
I have no idea if a tiny piece of tape would work over the mist sensor, but you get the idea...just fool one of the minor sensors that has no affect on other systems.
