Cool 2000 E320 - flashing low fuel light

I have this random problem with the low fuel light. irrespective of the amount of fuel in the tank, sometimes the low fuel light flashes at a speed similar to an instrument cluster indicator flasher when there is a bulb blown (faster than normal flash). This problem is intermittent. It may not do it for a few days then it will flash all day, regardless of whether I turn the ignition off to try and reset. Anyone have any ideas before I take it to a dealer?

That's the way I understand it too.

Check Engine comes on if you let it go too long.

Flashing fual light indicates that the fual cap is not on properly or tight enough, unless their is a problem with the wire thats connected to the fual cap, that might make the low fual warning appear also.

thanks guys.... I havent tried the experiment but I dont think I need to.... the amount of times that I have found the gas cap loose, just resting, or even off completely after my wife has been to the gas station is anecdotal enough! I have pledged that "I" will be the re-fueler from now on, so lets see... the light should no longer come on.
cheers

yeah its most likely the cap...usually check engine light comes on with the flashing low gas but thats not the case here...also if you open your trunk and u remove the panel straight ahead where the back seats are there should be some wires that u should try moving cause they connected with gas...but just see what happens with the gas cap

Flashing low fuel light

I had the check engine light and flashing low fuel light come on. Tried a new gas cap and that didn't solve the problem. The mechanic I go to hooked up a smoke machine to the fuel system. It basically injects smoke into the fuel system so you can visually determine if there is an air leak. It turned out to be the evap solenoid. After that was replaced, no more check engine light or flashing low fuel light.

Where is the evaporator solenoid located ?
