I have an 87 GTI bought way-used & without owners manual. Does anyone know the procedure to operate the digital clock/instrument module? How to change display modes, set clock, etc. Buttons or controls for this electronic display are not obvious. Any hints would be appreciated.

It took my son to find out answer to this inquiry. The clock module is cycled by pressing "MF" (Multi-Function") button on end of right hand stalk (wiper control).
