Hi all! I'm the owner of a 2015 E220 bluetec , I've had for a year now and it's been fantastic , been to Europe 3 times already and never missed a beat. All this time it had a new valve cover gasket as it was leaking oil and a new water pump. For around a month now it seemed to have stopped using adblue , I do mostly city driving but have been on long motorway journeys and it hasn't used a drop of adblue! Tank is full and when I check the level on the cluster it also shows as full, any ideas what's going on ? No lights or error messages and I've had it scanned around 2 months ago and there weren't any codes stored.
