hissing noise coming from area around battery on my A4

[sionic]

Hi all,

I've got a 2000 A4 1.8 SE Automatic. After a drive the other day I had the bonnet up ready to fill up my washer bottle,
and noticed a hissing noise coming from the battery, or somewhere between that and the brake fluid container.
There is no steam coming from anywhere and i can't see any leaks, so i just wondered if anyone knows what it might be?
Maybe something in the battery?

many thanks,

Si

Nope its fine, Its from the orofice tube for the aircon. It lives under the battery tray.
