I'd have a really good look at all the connections. Make sure the connector pins are clean and they snap together firmly and lock properly. Modern electronics is usually pretty good, but connector technology is often the weak link. Ideally you want some proper aerosol switch cleaner, but meths will do if you find any obviously dirty pins or sockets.

I haven't done much work to my Octavia but there is an earth strap on the gearbox on many cars, worth checking for this. With so many warning lights flashing I suspect an earthing problem.
