My A4 Bj. 2012 wears like windshield wipers. The replacement took place so far in the Audi workshop, the bill is mounting with nearly 50 euros! Had then the wiper of Bosch found Amanzon and ordered - for the price a real bargain. Thanks to the simple closure I could quickly assemble and did not need to set the MMI (onboard computer) wipers service position - at Audi can be namely the windscreen wipers not even simply be folded down so as to swap them. Only briefly lifted the wiper, pressed on the click-lock, old wiper original Audi out, Bosch wiper pure, can click-lock into place - less than 2 minutes. The wiper performance is at least as good as the original, on the wear I'm curious. The last wiper Audi held by less than six months or 10,000 km away. Can actually only get better.
