As a quick update, I returned from over 1,700 miles from Laon and the Black Forest last week, with the overseer light on and off for the whole trip, but with no ill effects on performance. I also had the brake light going on and going off randomly, mainly when changing directions, but it didn't ever stay on and I couldn't see any obvious faults. I will get it over to our local dealer when I have time and report back for any others who may be having problems.
