1992-1995 passat and 1993 to mid 1997 jetta and golf, canadian models only, no US cars got the 1.9TD. They were also available in europe but I'm not sure which years.
The TDI was introduced in 1996 in the passat and in mid 1997 in the jetta only. The golf was not produced with any diesel engine option from 1997 until the A4 cars came out in mid year 1999.
