Hello I would be interested to know how long you drive with a wiping water filling? Because my EQE 43 has been 3’200 KM and has never had to replenish the wiping water… Previously on my VW Touareg, I had to fill up the wiping water in part every 1 1/2 weeks in winter. But was probably partly because he also had headlight cleaning…. How much liters of wiping water does the EQE have? Many greetings Marco
