My car must've had the Monday morning blues this week... when I got in Monday morning, all memory settings were forgotten: seats, pre-set buttons, unlocking of all passenger doors when the car switches off, etc. It was like the car had reset itself to its default.
Was in a rush to get to work so I just adjusted my seat and drove to the office, meaning to get in touch with BMW later. When I started it up in the evening, everything was back to normal - both memory seats, pre-set buttons, etc were as they ordinarily are. Problem hasn't recurred & hopefully it'll stay that way.
It was like the car lost its mind cos of Monday blues...makes it seem a little human.
