I replaced my bulbs about 6 months ago. Just go into any car parts store and use their guide/take out the old bulbs and bring into store to confirm the same number of filaments, size, etc. i realized the Audi has so many different types of bulbs and you don't want to put the srong ones in wrong socket.
