Hello, I experienced a nasty surprise in the middle of the highway during the Sauwetter: Wipe water all. Since I have the exclusive version (with Xenon) I had assumed, of course, that among all the gimmicks in the display there is also a corresponding warning – but gauze, wrong thought. And that also does not seem to exist as retrofittable accessories. I always thought at Xenon there would be heavy conditions for the manufacturers – because of forced cleaning of the headlights n Ach 5 x motor start, after every third wiping or similar nothing at all! You can look on a poppy plastic strip, if there is still enough wiping water in the container.My first car without wiping water alarm! Is this somewhere from anyone to retrofit?
