Hi everyone , I wonder if someone can help explain to me how the 3x bolt/spacer system works for installing the headlight units themselves ?


I need to put the two headlights back into a 2008 A6 , that i didnt take apart and i cant for the life of me figure out how the system works to adjust the gaps and lock the headlight units in position .


Every time i try to screw the headlight in .... the L/h thread spacer thing just unscrews and comes out .


Ive tried searching , but i keep drawing a blank .... pulling my hair out here , and i'm sure its really straightforward ..... but , everything seems to be all about beam alignment , or xeon conversions .... i need an idiots guide to basic getting them in place and looking nice before i attempt the bumper install .......


cheers , Ian
