 Oh the beetle and its quirky electronic issues.  Yes, that is the joy of owning one.  You never know what light will come on or when it will just quit-even when it is brand new.   An adventure in driving!  A leaky sunroof, a dead transmission, faulty cluster gauge, bad starter, vac leak, oxygen sensors out. The list is so long.  I grow weary of it all.  Suffice to say just don't take the VW trip unless you want to spend $$ and time at the dealership.  P. S. They told me not to worry if the check engine light was on-only if it flashed.  A great comfort indeed.
