I found a new fault this morning when flying the A319. After departure i selected the A/P engage and it would not automatically follow the line displayed on the ND, so i tried resetting it numerous amount of times and pushing the HDG knob many of times with no success. In addition to this, the ND wont reconfigure when passing a way point therefore still displays the previous way point in the top right corner. To display the next way point i would have to select it in the MCDU manually.
Small but annoying problem.
