Hello this is my first post im in the UK and it would seem other than the Dealers there is very little help out there for problems with RB4 dash clusters

My 2004 A4 2.5tdi convertible had a voltage shock which took out the dash it originally broke down due to fuel pump failure

1) The Ecu has immobilizer removed
2) the Fuel pump ( which also has an immobilizer code) is new and virgin waiting for code 
3) The dash is used .

I need to extract the skc pin code from the dash before it will allow me to match the ecu to the pump

anyone any idea which software to use to extract the code

Thanks in anticipation
