Hi All I see various people have had issues with engine management light on and cannot read AD Blue fluid level being shown , I have this issue however at various intervals the correct reading shows, for example 8600 miles left which has now dropped to 8300 miles , the car drives fine however engine management light worryingly remains lit and it continues to show cannot read level intermittently. My local garage did a diagnostic check which confirmed it is AD Blue fault he was of the opinion it was overfilled and would rectify itself as level drops, after researching it , it appears you cannot change level sensor but it needs to be whole tank ££££
