Rear Wiper Washer not working

1 month old Golf Tdi, and the rear washer is not working. The pump is working, I pulled loose the line at the tank and has plenty of pressure. So I have some pluggage somewhere in the line, I tried shooting a little air in the line but no success. Any ideas, I know this is a warranty item, but I would like to avoid the dealer if at all possible. Thanks

Did it work before and stop recently, or has it never worked? If it never worked, maybe the factory kinked that long hose somewhere and it's pinched. If it was working initially, try to run it a bunch, then pop the hatch and see if the bottom of the hatch's interior trim is wet. I believe some folks have had the hose come loose inside the hatch. Maybe you could try poking a needle in the little spray hole and see if there's blockage there. (fyi: Later you can aim the spray by putting a needle in and moving the little sprayer nozzle.)
