96 TT my HICAS light went on the other day after going thru some water. I don't know if that has to do with it. But it seems to only go on when I make a right turn. Turned the car off, light did not come on when started. Made a series of left turns, that was fun, no light. made a right turn light came on. turned off the car light did not come back on until I made a right turn. I tested it a number of times. What sayeth the experts :)
