I have been looking at previous threads on this subject and some of my questions are close to being answered but there are still a few things that i need to clear up

firstly, should my car have remote central locking? it is a 95 a4 1.8 turbo sport. all i have are 2 plain keys.

secondly, i read that windows etc can do strange things if the central locking pump is damp. mine is dry yet my sunroof is going up and down and the postion switch doesn't seem to correspond

thirdly, the central locking doesn't work. i pulled the pump apart and put a live to the motor. it worked. i then changed the pump with one that did work but it does not work in my car. is this due to it needing recoding? i tried the key in the pax door but that didnt make it work either. i can hear a relay clicking in the pump unit but nothing else.

any help is greatly appreciated
