Adblue level on 2021 Ducato

[Shropshire lad]

I have a 2021 Ducato based motorhome which is pre digital dash. Is there a way to check the Adblue level?
Many thanks.

It is believed by some that as old adblue can crystalise in the tank to never fill it,others having read about lights/ count down not resetting when refilled...never let it run low enough for countdown to start... make your own choice!
( additives are available to stop crystals)

I have a 2022 model fiat ducato 140bhp last year adblue fault came up when in dealership for hab check,l have a digital gauge and thought it did not use much,long story cut short m/home off the road for nearly 2 months luckily under warranty new add blue injector fitted then new add blue tank.l now after reading on this forum 6litres approximately to 100 litres of diesel.lve seen other comment when the light comes on after filling it still won’t go out

This could possibly be down to the user starting the engine immediately after filling. We have a 22 plate Ducato based Burstner. In the Fiat handbook it says to turn the ignition on after topping up the Adblue but not to actually start the engine and to wait about 30 seconds to allow the system to go through its pre-flight checks (my words) before firing her up.

There is a difference between "filling up" by a cannister and a . Used properly (assuming the cut-off is functioning) the will not overfill.

Please check, but I have a recollection that adding adblue before and after a warning light requires different procedures.
