Help with Standard AU Radio Code

[Aufairmont99]

Hi all, sorry to revive such an old post but I’m having trouble getting my code from ford, did the usual crap with the vin number at the dealership and the keep coming back to me with the code 2146, I’ve entered this code twice and it is incorrect. Contacted ford with the serial number of my head unit as I believe it has been replaced with another standard ghia head unit. Does anyone know if it is possible to just go into the dealership with the serial number and have them retrieve it that way? Also I’ve tried contacting Fadi but had no reply, anyone know if he’s still doing the radio codes or if he has a new email? Cheers in advance.
Car is 99 au s1 Fairmont ghia if that helps for any reason.
