I am getting washer fluid error message every time the car boots up.
Two times I have reported this error to KENDALL AUDI of Anchorage and 2 times they
stated "we found no problem" but the error message persists.
This is maddening. Last service check they filled the reservoir up and the message went
away for 2 days then came back.
I think there is a broken sensor or the tank has a slow leak.
The Service Department should fix this.
Massively annoying that an $85,000 car has this stupid error.
(I have seen this error reported on other AUDI cars for many years into the past.)

There's a known problem that causes excessive washer fluid consumption. There's a software fix for it.

You are probably low on washer fluid. This is a software problem. Similar to you, early on in my ownership, I was surprised to find the fluid warning alert coming on when I know I had barely EVER used the washers. Be persistent with your Audi Service. When I first took it in they were puzzled until they actually talked to one of their Audi E tron Technicians (yes, the E tron has "technicians", not "mechanics"). Only he was aware of the issue. I was told that an error in the software caused the washers to dispense 10x the correct amount of fluid. They updated the software and refilled the reservoir.
