After my last car had so many problems i decided to scrap it and buy another, the main thing was that i had to be able to swap my k04 and matching ECU. So both cars are APU 1.8t one is Sep 99 and the other feb 2000. I have just noticed one ECU ends AA and the other AC. What will the differences be? I have googled it and a golf forum said that different numbers wont work even if i swap the clocks aswell. Is that true?
thanks for any help.
