Mate of mine went to his dealer to have the software update done so that the car remembers the last ASS setting. It's a 1 1/2 hour job involving plugging a cable in and hitting "start" (or thereabouts)
He's had his 328i for 3 weeks...
While the idea of remembering the setting sounds good, I don't mind the system personally so it's not an issue for me. But quoting that for a practically brand new car? Ouch.
