Hello, maybe someone can explain to me the following: Vehicle: Volvo C30 Bj 2007 I fill the container of the windscreen washing system brimfully. The container may be tight, because after some time the water level is unchanged (I did not drive in between). If I drive now for example 2 days, then about half a litre is missing. I did not make the washing system in between. However, I imagine myself to smell the sweet smell of the wiper water (frost protection) from time to time through the ventilation, especially after a quick bend ride. I do not believe, however, that the water overflows and can leak out at the closure, since it looks dense. Does anyone have an idea? PS: Although I don’t have xenon, the headlamps should also be cleaned, since these covers are present on the front bumper (in front of the headlights). However, there are no traces of a cleaning on the headlights themselves.
