Hi All,
I have an A4Q 1998 pre-facelift which has a dodgey LCD display and I was thinking about doing a swap.
I have read with interest : http://www.audizine.com/forum/showth...58#post6050358

I have cluster II, and I found the exact same cluster ( same part no.) and bought it to swap out. I have both original and donor cluster pin codes.
The original cluster has a 3 digit pin, The donor has a 4 digit pin. The value in Vag-com requires a 5 digit pin. Preceeding 0's to make up 5 digits are accepted as correct.

I have visited alot of forums to research the swap, and have followed many an article to swap out the cluster.
I followed the instructions from the Ross-tech website,
I have read and recorded the data from the original cluster, and loaded it to the donor cluster.
I have matched the donor cluster to the ecu.
I have also been able to correct the mileage of the donor cluster to match the original cluster.

I have tested and am able to restore the donor cluster to its stock state.

My issue is with the immobilzer.
I thought by loading the data from original cluster to donor cluster, this should recognise the key.
In the ODB software there is an option to learn keys, but I have not seen this being used for a cluster swap, but used for blank keys.

Have I missed a step in the procedure, does anyone know were I have gone wrong, or what I have missed.

Any help here would be greatly appreciated.
