How do you separate headlight lens from headlight housing in a BMW Z3?

To separate the headlight lens from the headlight housing in a BMW Z3, first, ensure the headlight assembly is removed from the vehicle. Use a heat gun or oven set to a low temperature to soften the adhesive holding the lens to the housing. Carefully pry apart the lens and housing using a plastic trim tool to avoid damage, ensuring you work slowly to prevent cracking the lens. Once separated, clean any old adhesive from both surfaces before reassembling or replacing components.
