I am using VCDS Lite and I have a bench test setup that I use to run the LCD segment test on Passat instrument clusters. When I use the same bench test setup with a 2005 Jetta MKIV cluster I only get a red horizontal line across the middle of the LCD panel. Are Jetta clusters not able to run the segment tests? Or, do Jetta clusters require a different wiring configuration than the Passat?
