information for anyone with same problem as me. screws were snapped or stuck and needed drilling out. almost impossible as dont have space to get drill straight on. in end removed boot panel and complete light/handle/key fitting to get screw drilled out straight. however while off was quite badly corroded so rang for price of new one. cost £37 new from audi. not a bad price i didnt think. mine on order as dont carry in stock. ordered leds 2 for full affect. just in time for clocks to go forward and noone see...........never mind.
