Hi had the car from new and when driving it will stop when braking at a junction or round about  it is not stalling, you cannot make it happen and it will be fine for a number of weeks (miles) audi have had it and say there is no fault with it, but there is, all the other cars I've had whilst they've looked at it haven't done this has anyone else had this or heard of it as I am worried that I will be left with an expensive rogue car !
