the reminder is dependant if you are the registered owner in the system. I wasnt, eventhough i was registed on myaudi and the local dealership as the owner. I called them and quote was halved. Bacialy, if th equote for the warranty is over around 400 and seems exptremely high, then its worth giving them a call to check. 5th year warranty should be even cheaper than the 4th. it was for me. i think around 100 cheaper.
