“Hello, for a few weeks now, I have been listening to light “water sounds” in my Ceed CD while speeding up or suddenly starting downhill somewhere on the left in the driver’s area. Sounds like water is actually moving back and forth. On normal ride it is not perceptible. Only when speeding up, braking or as already written downhill driving. At KIA the air conditioning system has already been checked, but everything was ok. Does anyone have any experience or tips on what this might be? I’m invited to the friendly one for the second time next week. Then the car stays there for a day or two.
