I am new to Audi and not sure if this is some sort of feature or if something is wrong. The doors will not lock manually. They work fine with the key Fob. For example, if i were to come home and noticed the doors were not locked and I don't have the keys, on any other car i would just open the door and hit the manual lock button and close it. On my Audi I open the door and the manual lock does not lock it. You can only lock it with the key FOB. Is this normal?
