I have an incomplete table on my site:
http://scirocco.cs.uoguelph.ca/gtd/VW%20diesel%20engines.htmEssentially it goes like this from a model perspective, (I'll conveniently ignore everything prior to '85)
1.6 NA (ME) motors can be found in Golf/Jetta 85-92
1.6 TD (MF) motors can be found in Jetta 85-92
1.6 ECO (1V) diesels cannot be found in Canadian models we did not get the 1Z motor here
1.9 ECO (AAZ) motors are in 91-95(?) Passat, 93-97 Golf/Jetta
1.9 TDI (1Z) motors are in 96-97 Passat
1.9 TDI (AHU) motors are in 98-99 A3 Jetta
1.9 TDI (ALH) motors are in 98+NB, 99+ A4 Jetta, Golf - not sure if these run through 2003 models or not.
