For sale is a brand new, unused, driver's side radiator fan unit, (see part number on box label pictured). It may not be the last new one in the States, but it is the last one in Audi USA's part database. I know this because I needed one and called my local Audi dealer for one. The part manager's search revealed there was (1) left in California, which I had him buy and ship to Utah.
Anyway, I know if you're needing one, you might be jumping up and down right now realizing you found one!!
