Huh... Guess what: it'* not listed on mine, either. In fact, I don't have the general AU0 listing for power locks, either; the only A codes I have are AAA, AK5 and AL7, none of which are relevant.
I'm thinking that they might not list RPO codes for equipment that is standard on that particular model, or which comes within another, larger option package. I haven't checked all my RPO codes to see if it would fall within another code on my sticker.
Maybe you get AU1 on your RPO sticker if you get a lower-level Bonne and then do a special order of specific options including the locking filler cap lid, above and beyond the base package.
