Hello guys! Wants to upgrade my TT 99 to Aerotwin wiper. Have already got all threads through. But where I have found no answer is if the wiper arms from the A3 to the TT fit because all the stuff for the A3 is cheaper. And is the wiper performance really so good? Have the A530S retrofitter Aerotwins on the original arms at the moment and I have to tell you the wipers! Have streaked from the beginning and that already at very low speeds! Is that normal??? really dangerous at night!!!
