Hi all , as per tittle been told that the aum engine is pretty straight forward fit to replace the ary motor in my 2002 a3 Quattro. What I need to know is what needs changing/ swapping to get the engine in and working. Been offered a complete 52000 mile engine with ancillaries and poss turbo for £500. So anyone done this swap and can point me in the right direction. Or give me an engine code that's going to be easier. Need to be safe with what I need before I spend the money.
