GL Fuel Gage Problems

When my 2009 GL450 fuel gage reaches just above 1/4 the fuel gage drops to 0 and the "range to empty" reads "---".
No response to removing the fuel cap.

Welcome to Benzworld, to understand what is causing this, ie fuel guage on instrument cluster/ sender in the tank/ a sam unit/ wiring problem etc you will first need to read out the fault codes. The fault codes will put you in the right area to start diagnostics.
