When i went to Ptbo Nissan they were like WTF? Just got one of the mechanics to say to the lady that its not the proper engine in there.
She had no idea what to write so i just told her to state that my car with the vin # and that it has an engine in it that was not offered in north America.
Printed it on Nissan letterhead, the mechanic then signed it, Done.
O and it was freeeee 
Just go in and talk to your dealer…
