Hello, I am new to your forum.My wifes' car is a 2002 E-320 4-matic wagon.Recently the low fuel warning has started to flash at 3/4 of a tank.Can you point me in the right direction? It seems to be an intermitent problem.Thanks for any help. Robert

 

youve got a problem with the evaporative system. bad gas cap, bad shut off valve at the charcoal canister, something is leaking. could be a bad fuel preesure sensor or level sensor.

 

Thanks for the direction.I will see if my wife forgot to tighten the gas cap. Best Regards Robert

 

normally the the check engine light will come on, if there is a problem with the evaporative system. so that might happen soon too.
