Hi, have just brought a 2009 a3 3 door, I have noticed there is a weird issue with the locking, when unlocking by remote the passenger door wont open from the outside, I have to open from inside, after opening from the inside it will open from the outside until it has been locked. when unlocking the doors I can hear the central locking motor inside the passenger door, also the fuel cap never locks, so when I lock the doors the fuel cap can still be opened.
