Hello, since about 1 month I have a used V40 1.9D Sport BJ 2002. The car has 37tkm down. If I drive on the country road and turn off the radio I hear a noise when (quickly) let go of the gas pedal (to switch) as if something is ventilated or a flap is shut too slowly.. I don’t know exactly how to describe it but if I go off the gas there’s just this hissing. Do you know that maybe one of you? Maybe this is normal with a diesel? The used car dealer (swab garage) has made completely TÜV and so. Have also 1 year warranty. Do you think I should have another check something there? Thank you for your tips. Greeting, Marco PS: my current consumption: 6l with fast driving! Really great of the cars !!! (115hp)
