Bryan,

The buzzer is about as loud as the horn so you have to be listening.  It
doesn't always come on with the light.  I -think- if the light is just
flashing, there's no buzzer, if its on solid, there is a buzzer, but
check your owners manual.  Basically, the manual says 'if its blinking,
have it checked asap; if your hear the buzzer, pull over'.  Mine has
done that trick a few times.  Only at redlights, basically when
accelerating away from them.  It always has happened when 1) I needed an
oil change, so it was probably thick oil; or 2) right after an oil
change and/or addition of oil that made it have too much (as indicated
in a recent discussion, most vanagons tend to like their oil between the
1/4 and 1/2 mark on the dip stick, not high).

Personally, I wouldn't worry about it unless it continues.  Although
that dealer did rip you off on an oil change.  Mine charges $19.95
including the new filter (and did the pressure check after the first
light incident for free).

Hope this helps,
Tonya
