central locking system

[Jiri]

hello guys,

does anybody know when you change the pump in the back,you have to recode the pump and key?

I already change my battery of my key.

my central works with my key in de lock but with infra red he doesn't go.

I'ts a audi rs2 1994

As far as im aware you shouldnt need to code the key. I know its not an RS2 but ive just changed the central locking pump on a 2.6 coupe and didnt have to and ive changed the pump on my 95 S2 Coupe and not had to do it on that one either. Yours might be different tho

You must be sure to replace pump with exactly the same pump (part number), because B4 got pumps with different functionalities. If you replace only pump, you don't need to code anything. Pumps with ability to code starts with late 97.

the pump i replaced has the same number,
maybe it's my key transponder that doesn't work are there any possibilities for control the
sensor on the door?

There was a procedure on re-matching the keys...
I think if you unlocked the door and then held the button for some time, something like this...

i agreed i aslo read somewhere long time ago

[Jiri]

does anybody know where to find the re-matching again?

If is the right central locking pump you only need to syncronise the infrared remote. I think you can use vcds for that.

for people that have the same problem here are the steps you have to follow :

Do you have memory seats as well? If so follow these steps I am going to refer to the keys as A and B as you have 2 of them
1) Unlock car with key A
2) Turn ignition into ON position with key A and roll down the window
3) Point Key B at IR Sensor and Click twice (perform both clicks under 5 seconds)
4) Turn off ignition and pull Key A out
5) Turn ignition into ON position with Key B
6) Point Key A at IR Sensor and Click once
7) Turn off ignition and Pull Key B out

Key A should be programmed as the Master Seat Program and Key B should be programmed for the Secondary seat program
So when you set your memory seats Key A is for Memory Position 1 and Key B is for memory position 2
if you don't have memory seats then you only have to point the receiver at the sensor and click once. That should just sync the IR Frequency and Codes
