Hello, at the moment it happens again and again that my gearbox does not switch clean (e.g. from the 2-speed to the 1-speed). Now I asked the dealer what a software update costs, so that the error can be fixed with this “small” measure. The costs amount to approx. 90-100€. And I thought that you only connect a computer and overplay the software. Who also got problems with the Geartronic or a software update? Reviews are gladly desired t! Greetings from Berlin, Michael
