I have a 2008 A6 and want to adjust the direction of the windshield washer fluid spray nozzles. The nozzles appear to be housed under small black housings (pic) that may be just snapped in place? When the housings are removed are the nozzles adjustable?

 

My crappy C4 has four nozzles - 2/per side - under similar plastic housing. I don't know if those housings are coming off or not, but never bothered to even try.
I adjusted mine by simply using a sewing needle.
Insert it in each hole and gently move the nozzles to aim to the desired position (try to space the spray patterns equidistantly over the windshield's surface)
