Just replaced the Offside dipped headlamp lamp. Tried trough the wheel arch flap but you'd have to be a contortionist with small nimble hands to do it that way.
Changed tactic after reading this thread and removed the air-box (6 off T25 torx screws to remove the top cover). Remove air filter and front top hose. The bottom box is held in place by two rubber bungs at the back (visible) and one into a clip below the box (just about visible through the front grill - Remove bottom hose then pull up on the air-filter box base to release this from the clip. Wriggling the box and pulling hard may be necessary).
Note: there is a drain hose below the box.
Now you have better access to the rubber cover and the lampholder. Twist the lamp holder 1/4 turn anti-clockwise looking into the back of the lamp and lift it out of the headlight fitting. Note its orientation as you remove it so you will know how to present it to the headlight fitting to fit it back in.
Pull lamp out of holder (has a small clip and might be tight on the electrical blades/socket), push new lamp into holder, fit holder to lamp housing (fiddly to get it right - I started of in the 1/4 turn position while looking at the lamp going into the housing from the front.) When its in turn it 1/4 turn clockwise to lock into place. If it does not feel secure then remove and try again.
You'll know when its right.
Refit rubber cover, then bottom of the air-filter box (fit the back bungs in first then the bottom one by moving the hose out of the way and pressing back and down on the bottom of the air-filter box) Check it has seated correctly by looking at the bottom bung through the front grill.
I have no idea how to check the drain hose is fitted correctly to the underside of the box, but hopefully it will slip onto the spigot below the bottom of the box.
Fit the bottom air intake hose, then the air filter then the top of the box (6 T25 torx screws) then fit the top hose. Tighten the hose clips and it's done.
It took me about 20 mins to it this way just as dusk was approaching.
Good luck
