if you put it in thre tiptronic mode it doesn't matter if you don't need it, if you have to come to a full stop then put it back in automode, I'm not sure its a gear selection problem so much as a 'gear engagement' ie clutch type thing - it seems to almost freewheel up to a junction/roundabout doesn't seeem to be any engine braking, I've driven two auto galaxies and both have been like it, there has been some discusssion about it before on here IIRC
