Quick one guys I can hear the motor engaging when pressing the the stalk for the jets to spray water but nothing coming out. No water leaking when lifting the boot lid is it most likely a blockage with the nozzle? Want to attempt to sort myself if it is a simple fix but car has warranty so if not the case can book in with Audi.

Rear wiper washer not working
Re: Rear wiper washer not working
I am assuming that your front washers are working OK.
First thing does the washer motor sound as if its under load (pumping water) or just free wheeling at high speed? If its running fast the impeller my have come off the motor spindle.
The washer motor pump operates both front and rear washers and a valve on the bottom of it switches which either front or rear depending which you select just by changing the direction the motor spins.
Otherwise take the rear wiper spindle cover off, then pull the spray head part out, its held in with an O ring.
Try the washer again with the nozzle out and see if there's water coming out.
If not, the water feed goes straight through the wiper spindle from the inside, so If there's no water leaking out of the boot maybe it is collapsed as it comes through the hinge.
Unclip the off side boot hinge cover and check.
Lastly the washer pump itself, jack the off side front up and remove the wheel. Remove the wheel arch liner (dont break the clips!) to access the bottom of the washer bottle.
Pull the washer pipe to the rear washer off the pump and try again. No water, faulty pump. Part number 1K6955651 I think.
If the pumps working to the rear, start looking for soggy carpet inside down the drivers side from front to back!
Best of luck and wishing you a sunny day to do it on
I hope this helps

Re: Rear wiper washer not working
Hi Jools many thanks for your message I worked on it yesterday following my initial post. The front wipers are working I removed the cap off the rear and the nozzle itself sprayed some wd40 and water was free flowing got some some compressed air which got rid of some debris from the nozzle itself and now the water is hitting the rear windscreen and there is improvement put the spray pattern is not as fluent as I was hoping is it safe to say I replacement jet nozzle is required?
