Refilling? Is there a new breather valve?
I have noticed that the w205 has a metal flap hindering clear access in the fuel neck. This seems to stem the flow of the fuel significantly and I have even noticed that when I pause I can hear the gurgle of the fuel down the neck.
In my w203 I had a metal flap and on my w251 R320 it's completely open.
Any thoughts on what I am missing or doing wrong?
Thanks
