As per title, I am sure when I first got my Allroad I found in the menus somewhere how many miles were left before it needed an Adblue top up, but I cant find it now! Did I dream this - the manual states that there is such a function but doesnt say how to find it. Its a 2015 272 Allroad. I had my first warning a couple of days ago stating Adblue system fault and 650 miles left, but today the message has gone!
