2005 X type diesel 2.0. I have recently started to hear a hissing/air rush sound when accelerating beyond slowly. As speed picks up the sound goes away. There does not seem to be any effect on power but i think economy has dipped by approx 3mpg. Any ideas??
Many thanks for the help and yes, it is blowing black smoke on acceleration. If the EGR Vv was blocked would i hear the air whoosh noise as turbo is loaded?Many thanks for the help and yes, it is blowing black smoke on acceleration.

well, you don't really hear air when you press the brake pedal. You might hear hydraulic fluid going through the valves in the master cylinder, that sounds like air flowing through a vent. But, I assure you, it is not air.
One can press and pump on the pedal when the car is off and hear the 'rush' of fluid which sounds kind of like air rushing out of an inner tube.
It's a common mistake to believe a rush of air is being heard when pushing on the brake pedal.
