C5 Mk2 2006 Front bumper removal

[masood_ilyas]

This relates to a Citroen C5 MK2 2006, initially with a faulty orangish headlamp, now both main and dipped are dead, only the side lamp works.
I was advised by the nearest dealer (London NW9) that this one dipped headlamp replacement will cost me around £370 !
At this price I think it is worth having a go first!. I need to access the Ballast resistor and head lamp for inspection and replacement.
Could some kind person point me to a c5 front bumper removal instruction.
The one instruction page I have seen says remove the top panel, under tray and other screws but I am obviously missing a vital piece of information as I am unable to remove it free.
Any advice and help will be appreciated as driving around as a one eyed monster risks being stopped by the men in blue.
