Hello guys.
I was reading some old material about putting a FIS cluster in a 99.5 car.
In the reading I found Jetta,97 talking about manually adding a key to the immo3 clusters as adapting without a immo3 ECU will not work.
I would like to do this for my bench setup and to possibly use locked transponders again. but lets take it one step at a time.
What I have tried.
-I can say that you cannot adapt keys to a immo3 cluster without the ECU.
-I have connected my coil reader to
Green connector
pin - 2
pin - 17
-I have read the key info from a cluster it was matched to.
_______________00 01 02 03 04 05 06 01 08 09 0A 0B
offset "0000020" FD 11 81 7B E8 4B 91 D7 0A 71 07 72
(The offset seems to change in different clusters however you can tell its correct by the transponder ID)
I know that 0A 71 07 72 is the inverted transponder ID
I'm not sure what the first 7 bits are.
Simply manually adding these bits was not enough to make the key work.
I noticed that the offsets directly below the matched keys in the cluster seems to be important to the function of the immobilizer.
If someone like jetta can comment on wether I have the immo coil reader connected in the right way, or if I need to also transfer over the info below the keys in the eeprom.
Thanks guys.
