his happens, especially in the early Delphi ECM's. They just lose the VIN. The download is free but the dealer might charge you half an hour or a minimum shop fee to hook it up. No big deal really. We get 2 or so a year that have no VIN. More common in 02 -03 Softails i've noticed. But I did have an '02 touring bike that lost it's VIN. I've even had them lose the VIN in the middle of a tune. Loaded MAPs on no problem, then all of the sudden, nothing.
