I have changed my old 1.6 Diesel to a 1.9 from 1999 in my 1983 VW T3 bus. The engine code is AEF and it can be found in VW Polo, Skoda, Seat and Audi. When I started this conversion I was suprised how little information it really was about doing this swap. So I made a video collecting this information and what parts needed and problems that I had to solve. So hopefully this will help others that is thinking about doing this conversion. Good luck!
