My Audi seems to have a peculiar malfunction. The washer fluid indicator goes off every now and then . Intitially, I thought the fluid was really low and took it to the dealer, got it filled again. Then it kept silent for a while and started to show up again with that annoying beep sound. This seems to happen when I am curving a lot along the road...like ramps off the highway etc....(but not always)...most of the times it happens when I do that. Any one knows what it is about? It is 2000 A6 2.7t.
