I traced out a schematic for the LED display's circuit board from my '84 camper. Some listees have been asking about these things, so I've posted a copy to my web site. It can be found at: www.ns.net/~sgreen/vw/display.html It shows what's really inside the gray box in the Bentley wiring diagram. Interesting stuff if you know how Op Amps work; pretty arcane otherwise. The page also includes a plea to those who would attempt to repair one of these things: DON'T, unless you're sure you know where the problem is, and you're sure you know how to fix it.
