What Color Is Your DEF Gauge?
In my 2011 Phaeton (Freightliner) my DEF gauge is made up of 4 indicator lamps arranged directly under the fuel gauge.
The leftmost lamp is bright green, the remaining 3 are light green; it is as if they are not lit.
So I assume I have 1/4 tank of DEF. But I'm not so sure that the left most lamp isn't just greener than the others.
i tried looking in the tank with a flash light, used a light scope, and tried measuring with a dip stick. It seems that is not full, but is difficult to actually tell from a visual check.
I know the left most LED will turn amber when it is real low. I'm just wondering what others are seeing.
Thanks.
