Most people who own Audi A8L 55 with ACC would experience the Washer Nozzles of the Lidar Radar (lazer radar) leaking washing fluid even when parked. The reason is after time, the spring that pulls the sprayer no longer make the seal tight between the nozzle body and the sprayer due to dull surfaces. The water starts to leak due to gravity that push the water though the tubes and leak out between the body and the sprayer.
If you change the nozzle, the part # which costs between $50 to $60 online. In other to change these 2 nozzles, we need to remove the nozzle water hose from the back behind the grill and the 2 tabs in front holding the nozzle, and pull it out in front. Or I fixed the leaks by putting teflon tapes to the body right at the sprayer body so that when the spring pulls the sprayer back, the teflon tape will act as a soft washer to stop the water from leaking between the nozzle body and the sprayer head.
