Jump or disconnect (forgot which) the reservoir level switch to check it,
change the multifunction sensor (when they go bad the board inside
usually cracks), if you keep getting the warning after checking/changing
all the "usual" suspects, it's time for a new cluster/board.  I wrote up
a page on this, follow the link off my main page.
If it is the board, get a used one (or cluster more likely, hard to get
someone to separate it), last time I checked Audi wanted around $800 for
a rebuilt one.
