Might not be related, but . . .
I saw these symptoms once on a VW that I'd stored for a couple of years.
Turned out to be a 12V battery with a couple of dead cells.  Completely
confused the tacho (read half scale all the time), indicator relay etc.  I
wouldn't think the computer would be too keen on low volts either!
