AdBlue Discussion and Issues
Just stick with what I know! Evidently the adblue consumption increases with the update also.
Yes, from the information that I could gather, the sole purpose of the update is to increase the usage of Adblue as the engines didn’t meet the standards necessary (dieselgate). That was why they agreed to give out free Adblue
i had to do my first adblue fill last week, filled from a pump in Germany (about a third of the price of a plastic container). filled it to the click, which was slightly more than it said was needed on MFD..getting back in, I forgot about the 30 second rule and just started and drove away...adblue range had gone to max (9500 km). no problems 
No difference otherwise except no more engine warning light ( 5 times in 11k)
Performance, economy unchanged
My T6 Van shows the Adblue as 4500 miles to go. I know this is not correct, it just seems stuck on this reading, the gauge sensor must be poor. I suppose it will flash up a warning soon, telling me to get it filled.
Love the van, but this is a crap system and is causing no end of grief for a lot of us.
Disappointing indeed.

just noticed your speedo looks ‘cleaner’ than mine, as it doesn’t have KMH on the analogue dial...... weird.
Which dealers are you using?
these problems are with my caddy hence the speedo difference
So the new transporter I have or 15 months old has been back with the dealer SIX times now with ad blue error.
Just a recap...
First time the updated the software...
Second time they had to get the factory to dial in and update parameters
Third time they changed a sensor
Fourth time they change the ad blue tank
Fifth time they changed the ECU
And now after about two weeks since the ECU was changed the ad blue error came on.
The van is still under warranty, thankfully. Wondering what me rights are if I ask for a replacement van.
Clearly there is an issue with the transporter and the ad blue system.
Just really frustrating when they can't seem to fix it.

I have heard tales of Adblue tanks being topped off with just water when drivers have been desperate. I guess to stop a vehicle being stranded it would work. Not sure of longer term consequences, injector & pump corrosion etc... This was from a colleague who was an agency HGV driver and didn't have a way to claim expenses and wasn't going to buy Adblue from his own pocket, so topped up with water !
Pretty sure there's a quality sensor in the tank somewhere for exactly this reason, you can't fool it with water.
Reducing agent quality sensor: urea concentration: X%
