hi guys..i have a 520i 24v..i read somewhere that if you lock your driver door with the key and hold it,an open windoew will roll up by itself..is it true? ive tried this many times and nothing happenned..so i would like to know if this feature is available for all E34s or only for selected models...or is my technique wrong? i jus turn it to lock and hold it for about 10 seconds and give up..:motz: anyways heres a video on youtube of a fellow E34 owner dong it... http://youtu.be/4A4uiCbUYH8
