Hi guys and gals, my brava has just developed a knocking noise from what sounds like the front end, it is speed related, as it increases and decreases with the speed of course but it goes away under acceleration and braking, any ideas would be appreciated, thanks, :worship:

Try jacking up the car and turning the wheels slowly and look for any movement.
I found my knocking noise this way, turns out mine was the wheelarch liner catching on the driveshaft.

What kind of knocking is it? Metal on metal knocking? (I hope you know what I mean, it's currently 4:10 AM)

Problem solved, did the first thing that should be done and checked me nuts, lol, completely loose, do these cars have a problem with the wheel nuts coming loose or was it just bad installation by the previous owner, thks

Probably just bad installation, I have never had problems with them coming loose. If you have access to a torque wrench, they should be torqued up to 86nm (63 lb ft)
