The Dispatch | Expert | Scudo Hub

`Hello, sorry I am a bit late for the party on this as well but it may help someone in the future.....
My '67 plate euro 6 dispatch has adblue. The first time the adblue light came on and the dash told me I have 1300 miles before immobilisation I left it a hundred miles before topping up with 4 litres. As far as I remember the light went out straight away and everything back to normal.
The next time the light came on I left it for 400 miles (Down to 900 before immob) before putting 4 litres in. The light stayed on... so put another couple of litres in, light stayed on.
I then put all of the 10L of the bottle of adblue in and the light stayed on.
I took it to a friend who is a mechanic and he put his OBD reader on it and it showed no fault. Getting a bit panicky about having to book it in to a garage and looking at the costs of a new adblue tank at £750 was worrying when on a trip to town having done another 100 miles since filling, the light went out!

I think the moral of the story is, when the adblue top up warning comes on, fill it as soon as possible. The tank holds 22L so bang 10L in, don't panic if the light doesn't go out straight away.
If you leave it until you have 50 miles left before filling it, it may immobilise itself even though there is plenty of adblue in it!

I am going to try to put a splash in every month to keep on top of things, I did see that the mechanics OBD appeared to have an adblue tank level indicator so this can help if you have one?
