Adblue and my passat

[RayPike]

My passat is complaining about adblue running out. I bought some and put two litres in. It's still complaining about adblue running out. Surely this isn't a dealer job?

User error then. Been away for the weekend and got back to put in more... and more... and more... and entirely 10l bottle gone! Maybe the "Min 1, Max 2.5" message meant gallons then! Problem sorted, it reset itself after I filled it right up. For those interested, I've just passed 5,000 miles in it for that refill.
