Just looking for an overall sense of how challenging this is likely to be. What level of skill is needed? Is it necessary to remove the front bumper to do the job (as rumoured)?
I believe bumper off is a given - it's not difficult to get off so long as you know where the fixings are.
Worth signing up to the A8Parts forum (as well as contacting them for a 2nd hand light unit if you need one) as there's loads of technical guides available for common tasks
