My 2003 Jetta GL TDI sedan met with a guard rail and shall never see the highway again. I bought the car back from the insurance company because the engine still starts and runs strong. I have since picked up a 2002 2 ltr gas Jetta GLS wagon with a clean rust free body. I am interested in swapping engines. I am now just starting the research on how to do this. So far it looks as though the mechanical portion is the easier half, I'm only now learning about ECU's and immobilizers. If any one has recommendations/experience I'd appreciate the advise.
