I thought I'd give an update.
The cover at the base of the wiper arm unclips and I found my nozzle jet fell out. I confirmed that with the jet off, water was flowing. The little nozzle jet thing you can pick up a pair of for under £5 on eBay.
Problem solved!
Hi,
Recently picked up my first Audi, 2015 A4 Avant diesel. So far driven it about 600 miles and enjoying very much.
Only niggle I can find with it is the window washers. Front passenger side is very sluggish and rear window just shows a little dribble around the jet. Any tips?
Cheers
David
