Mine usually only shows full after a short drive and not at the time when I fill it. Mine takes 23 litres, if yours is similiar it may not be full anyway?

Thanks for the reply. Mine probably takes the same amount but I got the service done about 4 months ago and only driven about max 3000 miles since then so EML light came on for Nox sensor and I wanted to make sure I had enough adblue also so topped up and kept poring it in until it started pouring out to make sure it will full. So it took roughly 15 litres. I wasn’t expecting it to take this much in 4 months. I have an appointment booked with local merc garage in few weeks let’s see what they say about the light. My mpg has dropped quiet a lot to 35 mph

I've read similiar story's on here of the same fault after a service because Mercedes have updated the software in the ECU after the emission cheats. Have a search and you might find them.
