Is that the way for the late model Jetta (if we are even talking about a late model Jetta)? I just replaced the headlights on my late model 99 Golf. I thought I could access them from the back of the assembly, but due to my lack of agility I could not do it that way. I had to revert to the method in the Bentley which says to take off the grill, then the bumper, then take out the light housing, and change the bulb once the headlight housing has been removed from the car.
The method seems to be the same for the late model 99 Jetta according to the manual too.
Of course, I usually do things the hard way. :o/
