Hi,
on my previous var, 2014 F30, I coded the ASS memory. Whenever I changed driving modes, the car "forgot ASS memory" -- exactly as you described. Having said that, however, if I was driving in EcoPro & shut car down with ASS off (ie, the red light on). When I started it again (I also coded car to start in EcoPro), ASS was off (red light on).
Now that I have coded ASS memory on my M340, the same occurs. This is the normal modus operandi for ASS Memory
Hope that helps
