Strange Adblue Warning

The other day I started getting Adblue warnings, which I guess is normal once it gets below 1000KMs. After the warning was down to about 900KMs, the warning stopped. Now I'm getting a warning that says 2400KMs remaining. Anyone seen anything like that before? I'm concerned if something is wrong with the level indicator, it will suddenly think I'm out.
Couldn't hurt to fill it up now, I suppose? Assuming the level indicator starts working again.

You're in the bottom portion of the tank either way, so I'd just dump a jug in there regardless and continue on your way.
If you still get the warning with a fresh 9.46L in....then you know you have something to address.

A sudden warning at 1000 km left is not normal, it's an indication of a fault in the AdBlue system. But if it reset to 2400 km the that's the normal low warning indication. So dump in a jug, and if you can have someone scan for codes. This could be an indication of water in a connector, do you have a sunroof?
