My friend Alex is a mechanic and we are going to put a 2002 TDI in my Mk 1 Caddy. I am new to this forum and not quite sure how this whole thing is going to work so here we go. My 1.6 recently gave up on me and I decided it was time to put in the TDI. He is a VW mechanic so he is somewhat well versed in this arena but he said I need to learn as much as possible and we thought this would be a good start to see if any of you have done this sort of swap and if you had any advise, be it good or bad, that you could share with us. I will be posting problems we encounter along the way and let you know our progress. Wish me luck!
