I have client with E90 335i N54. He replaced DME/CAS/Key with a donor car. Car will not pass emissions due to miss match VIN. Client has OEM CAS and key only, Old DME is no longer present. With Autohex or HexTag is it possible to read ISN from CAS and write to doner DME then program to change DME VIN so all modules match?
Thank you!
