Hi Allan

A few things of interest here, mainly what caused the DPI (dash) to get fried in the first place?
Has it possibly been caused by a recovery jump start after the original non start condition in which case once the dash is working again are you back to the original fault?
Or if you start the car will it fry the dash again?

You cant retrieve the required PIN with VAG-COM so if this is needed then you're stuck. Autologic or possibily your local locksmith can get this for you.
Programming info here http://wiki.ross-tech.com/wiki/index.php/Diagnostic_Procedures#Immobilizer_Information

Personally I avoid DPI repairs and the programming issues you now have are part of the reason for this.
You dont know whats been removed,possibily part programmed before,what data needs replaced or if you'll have any compatability issues?
Too much important info to be messing about with for me.

Regards
Sean
