    Hi,

    Just noticed that there is a whooshing (airy) noise when I apply the accelerator on my 2004 E270 cdi. No loss of power is experienced but I can definitely feel air coming through the vents.
    It doesn't seem to matter whether the air con is off or on. Has anyone experienced anything similar?
    I would appreciate any help or steer or this.

    Thanks
