so to easily figure this out, literally take out your passenger seat and see if the audi seat fits. If not, measure to see if the bases are swappable.
if you get this far then I wish you good luck in figuring out if the seat weight sensors can work or can be made to work. if not, you are taking a chance on your airbags going off or not going off (especially the passenger side - not sure about the driver's side per se).
best wishes for you finding a solution / workaround!
