Re: Front lighting issues.
sometimes the light lens can come off the adjuster as the plastic can get brittle and it snaps (bl00dy Germans, Hella lights), it would be unusual for both to go at the same time though. If this has happened you should be able to feel play in the assembly the bulb sits in.
Yo remove the light altogether, take out the grille, two bolts from top, and 'unpop' the fixing at the bottom, there is not alot of inherent strength in the grill so be careful on the thin bits under the lights. Then its just a matter of undoing the three 10mm bolts, unclip the indicator, a big clip from inside the bonnet and its loose, disconnect the wire and take out.
