Odd idiot light on this morning

[Danton J.A. Cardoso]

Shrinkage?!?!?! As in being in the pool, and the water was cold?  How
in the hell can G2 shrink?  Then again in the fatherland they don't
get minus temps.... but doesn't Audi do testing in Siberia or some
place that it gets cold?  Funny thing about all this was, last year it
didn't do such a thing and it was damn cold.  How does -15 sound
without a windchill?  Nothing beats living in Northeastern Missouri.
One day it can be in the minuses, the next 30 plus degrees.  That of
course, the winter....

This combined with some possible minor normal coolant loss over the year is enough to set off the low coolant warning light when the temperatures drop significantly. I believe it's in the manual (I don't think it just appeared to me in a dream but who knows at my age.)
