Hello to the forum, with many previous VW models (VW Golf o.a.) you could set the interval time of the front wiper, in which you turned off the wiper lever for the too long interval time and then again again. And exactly this time was then used for the interval wiper. Does anyone know why this in the Up! (model move, year 12/2011) doesn’t work anymore, whether you can continue to retrofit it cost-effectively or what it would cost?
