As some know already, picked up a 2005 E90 330i for the missus on Saturday & am now at the "play with the buttons point".
My 2006 E91 locks automatically when you drive off & hit about 10mph, this one doesn't. Sounds a bit insignificant but it's a feature that the missis quite likes (I guess it's the lone female with kids thing).
I've been through the menu's in her BC & in the "Set" part with the key symbol, mine has the option to activate/de-activate this but hers doesn't (the fonts on her BC are slightly different too).
Would this be a software thing due to hers being a year older than mine or does anyone know if this function is accessible somewhere & can be set?
