Moin, the day after tomorrow is the meteorological autumn beginning and the muddy weather is already in the starting holes. does anyone know an even cheaper source for the front wiper Bosch Aerotwin AR650S or A650S? I wanted to strike first in the electronic bay and at the Amazon for approx. € 18.20 (incl. shipping costs). I then tried some price search machines, whether it is still cheaper and was surprised. From € 6,67 incl. shipping it starts. The Bosch product “A” not “AR” is also available for € 9.00. Funny! We already have Aerotwins from Bosch on the 107 and Aygo. But I want to be sure again. According to Bosch-Page, AR 650S is the retrofit kit. There seems to be this quick adapter with it according to the picture. A 650S is according to the description for vehicles that are already equipped with these in the original equipment. Do they not have a quick adapter? Do I have to pop the adapter at the old wiper first and pick up the new one? s: Is the A-series just the wiper rubber? ciao Metallics
