Looking from the front of the car....under the bonnet left hand side at  the back you will see the brake servo...look down the front of that deep at the side/back of the block you will see a few hoses put your hand down there and it is there...there is also a small plastic air pipe attatched to the top of the hbv,,,find that and follow it to the hbv..

I have changed 2,  a v6 and i4
The 4cyl is by far the easier one to change,

I removed the pipe connected to the heater matrix so I knew what way it went back in ( yes I have put one in backwards and had the heater dials work in reverse, not good )

anyway with that pipe connected to the hbv you can use it to pull the valve up to undo the clips, the pipes are very plyable just dont be rough

When it all back in I ended up under the car to redo the spring clamps with a pipe wrench, and you can reposition the hbv if its twisted

Found the little bugger this morning, luckily it,s nice and dry so that,s a bonus. The reason i asked is that i had a new rad fitted last week and i,ve had to top up a small amount. Will just keep an eye on the level for now as it looks to have settled.
Thanks to flyer and frostbite for the info. :y

Normal if not bled thoroughly  :y

Crack the cap and run it with cabin temps set to Hi for a few minutes and top up accordingly once done... :y
