My references Mit1 and Alldata gives me the same location for the starting relay both for A8 and A8 Quattro

Also there's no neutral safety switch for both-The starting circuit starts at the ignition switch then thru the starting relay and straight to the starter-after the central locking and alarm system/interior light delay module located left side of luggage compartment near wheelwell grounds the starting relay to complete the starting circuit.
