Hello I'm new on here as I got my first audi
So hi and sorry if it's in the wrong place
Well brought my a3 (old shape) knowing it needed bit of work. I have done most of it but one part as baffled me.....the central locking pump. So got a used one pluged in and it locks all doors when locked from driver door.but when I put my circuit in there it makes it sound broke and don't work. But the windows open from fob. So put old circuit bored thatcame in it so it will lock off the door.
Any advice will be great
I even tried taking the white thing off small board onto mine but still no joy
