When was the TDI engine introduced into the Golf. I read a few places that it was introduced in 1996? The owners manual for my 96 Golf says it's has 90 HP but I don't see TDI anywhere on the vehicle and I'm sure I saw AAZ stamped on the cover of the timing belt. Did the first TDI's look much different from the 1.9 IDI's??Also is there any way in telling what Model of Golf I have? GL or whatever? It's not marked on the ownership etc and there are no badges on it either?
