Copenistas, The problems associated with the Copen folding roof constantly reappear on this forum. Does anyone know if there is a diagnostic tool available that could quickly identify problems like VAG device. At one time I was a process engineer and programmed digital control systems. If a sequence stopped half way through it was relatively easy to identify which element had hung up and why by examining the rungs of the program on screen. The permissives seem fairly straightforward; Are the roof catches released ? Is the hand brake on ? Is the boot switch made? Yes? Then lower the windows ? Are the windows all open ? Yes, then opens the boot Is the boot open ? Yes, then start the hydraulic pump etc. Is this all written down anywhere ? Your thoughts ? Ned
