AdBlue Discussion and Issues
It does last a little while.It's hard to disagree - I couldn't put up with that.
If its any reassurance, I hear they burn very well.
Perhaps this might be worth reading?
[T6_measured] DPF regeneration vs. short journeys
Got curious how T6 copes with doing short journeys. And how short would be too short for successful DPF (Diesel Particulate Filter) regeneration. The graphs below are result of doing short journeys - the plotted one is number 3, thus two interrupted DPF regens before this. At this stage the...
I have 4 years old T6(150 tuned to 190) with quite significant mileage and I never have had any issues relating to EGR, DPF, ADBLUE.

This is the first time since buying the van that I've had to top up the Adblue, I got the 650 mile warning with 5600 miles on the odo so its very frugal and £17 for 10L at my local petty station isnt bad if it lasts that long. Display now says 6000 miles of Adblue. No hassle at all. I read the label on the bottle and it really is 32% pee and 68% deionised water! 
Yep
So this happened yesterday.
Adblue was topped up less than 1000 miles ago. so I’m assuming this is a common fault.
My questions are
1 Is it an easy fix
2 What happens if I do nothing and just keep using the van?
I know it has plenty of adblue in it and I’m too busy with work for the van to be off the road.
Can I just ignore it and get it fixed at a later date?

It will get to the point where the van will not restart if the level is too low. Even if it is fullish the system will require re calibration
Don't ignore it!
Can you post complete VCDS or OBD11 scan?
This has happened to me a couple of times the last time it happened on a trip to Norfolk I called out VW assist (got the AA) there was plenyty of adblue in the tank but he squeezed in another couple of litres we carried on and the problem cleared about 15 miles up the road! No issues since! This has been reported on this forum quite anumber of times! The aa guy checked for fault codes there were none!
Overfilling has nothing to do with this problem.
And there is no such a thing as AdBlue overfilling causing SCR system faults.
Have a look below.

Took the van to the yard today. 5 miles down the road and the adblue warning light went out. Didn't do anything, never topped up the adblue, just seems to be a gremlin.
You have NOT got the Engine software update in 2019-2020, right???
I had this a few times and it popped up more and more often and then was accompanied with an engine light. Mine was EGR flow insufficient which pushed the NOx levels too high for the Adblue to cope. Put a new EGR in eventually.
