I filled my 2002 ML500 up with fuel last night the fuel gauge worked fine. I started it this morning and the gauge is showing empty. What can I do please help.

Do you have teenagers?

Did you leave it unattended outside last night?

Have you attempted to fill it again to confrim if indeed is empty?

Have you checked the fuses?

Do you still have your original K40 relay?

It is always kept in my garage. I have checked the obvious, it has gone down to 3/4 and 1/2 before this but it always fixes itself. I just thought somebody might have a easy fix.

Search on the ML forum.

Perhaps there are known issues with wiring or the fuel level sender on your model.
