Hello,
I am curious how can I adjust headlight washer nozzles on 89 Audi 90 coupe. These are the external fixed ones sitting on the bumper. Is there special tool, I am afraid to use a screwdriver/plyers to brake anything.

Are you talking about aiming the nozzles? If so, a very small needle will work best. Gently stick it in the nozzle's hole and aim it where you need it.
