It is true, what your mechanic said. The old E36/e46 had the turn signals as a separate piece (if you look at them in pictures you can see a line separating the turn signals from the rest of the headlight), so it was simple to just unscrew the orange turn signals and put in clears. Now however its all one piece like the Z3 or 5 series is. It looks alot more elegant this way, but of course its gonna cost us modders an arm and a leg to change. The usual way to do this is to buy a whole new assembly like alot of Z3 people have had to do.
But there are el cheapo ways of doing it by opening up the glue of the assembly yourself like socals2k said. me or some other member will figure this out once we get our cars
