I got a new hi-tech set of wipers blades on my car.
I think they're now available for most Audi models
They do hang over the edges of the windscreen slightly, but they work extremely well! Plus I have to say they're the only blades I have had that I actually like to watch working.
They are outrageously expensive, but safety is my main concern and like I said, they work great. Let me know if you'ld like a pair!!!
