Odd!  I have a similar problem with my '88 90 Quattro: when driving
through snow and/or slush, the engine check light will sometimes
come on.  I first noticed this problem years ago when I was
playing (i.e. 4-wheel drifting ;-) ) in the snow.  Nothing
seems wrong, and the light clears either by revving the engine
or by restarting.

I've ignored the warning but would like to know why it happens.
