Yes you have to remove the inner wheel arch liner. Can be done with the wheel on but easier if you take it off. It is held on by 2 plastic screws at the bottom that should pop out with a little leverage and a self taper near the top. 10 to 15 minute job.

My missus had an 05 plate Audi A8 and the only way to get to the bulbs was to remove the front bumper. Definitely a "take it to the dealer and pay them £20" rather than spending ages DIYing

as above
can be done without wheel removal or jacking up.
my exige sits low on ohlins so find it easier to lift car on trolley jack to give myself room.

remove liner as stated, slide liner down as theres a piece of aluminium at top of liner that slots up into
recess.
then undo the 3 allen key bolts (not the nut/bolts-they hold the light housing in place) and gently lift/slide the plastic lense cover off lights/car, being careful not to scratch the body.
unclip electrics, undo pinch clip thats holding bulb in - replace -re-attached -re-fit

do a search on mloc wiki for a few diagrams if needed

I do not tend to do my own work on car, but changing the bulb was easier than I thought, getting to the top allen bolt was tight, and you need a hex bolt to undo ( technical numpty soo no idea of its real name!)
