Adblue

[rom1]

Got a message saying top up Adblue, when I checked the gauge it shows half tank left, I topped it a few months ago but have hardly driven car, no obv leaks any where.

Should i top it it or do I need to get it looked at ?

How much did you top up? completely fill it? or only a small top up?

Complete top up left a little bit off so it was not over filled,

Booked into MB Leicester under warranty, was a faulty upstream NOX sensor, and the topped up the Adblue which is full again, no charge and had a E220d loan car for the day.
