Hi all,
I recently had the Nox sensors replaced on my 2015 E220 Bluetec (A207) under Mercedes recall/warranty.
Before I had that done, I got the usual AdBlue low message on the dash and added 10L of AdBlue.
Today I decided it might need another 10L what with the tank being 25L in total, so I put that in today.
Then, after just a couple of miles driving the EML light came on. Obviously haven't had time to get the code read yet which I will do in a couple of days.
In the meantime, I am now worried that I might have overfilled the AdBlue if Mercedes also topped it up when they did the Nox sensors?.
However, I am told that AdBlue is treated like a consumable same as fuel and so its not filled as part of any servicing etc, so I assumed they didn't put any in.
The tank took the full 10L today and did not overspill, however i could see the level was almost at the top and probably just short of over spilling.
Can an overfill cause issues, even if the amount I put in did NOT spill over the top?
Thanks
Billy
