Engine Management Light then sudden drop in Adblue?

[scimmiamagia!]

Adblue level reporting 2500 miles left.

Engine management light comes on.

Suddenly 650 miles of adblue left?!

No performance issues.

Restarted the van and light remains on but is back up to 2500.

Any thoughts?

Rodent damage to the cable going to the sensor maybe? Might be worth a look if you can get the van on some ramps.

How do you find out if you have any adblue if the sensor is faulty? Not sure whether I need to fill it up or not. I have a 2500 mile round trip coming up so will take some with me just for emergencies but am aware of the dangers of over-filling as well as running out.

I’m not saying that is the problem. It was picked up on mine at the last service that the cable had been chewed. Although at the time it was still working ok I had it replaced. If you have a big trip coming up maybe you should get a garage to run some diagnostics and have a good look underneath for any cable damage, if only to rule that out.
