I have a 1996 S420. While driving my fuel gauge amber light starts blinking, indicating that I am almost empty. However, there is 1/4 to 1/2 tank full when it happens.

Also, while sitting at traffic light, suddenly the fuel gauge goes down to empty instantly. When I take off, the gauge slowly rise to proper level.

I am confused. What is the problem, please help? Please be specific

 

the fuel level sensor must be worn out and malfunctioning.

pull it out and check the variable resistor or contacts.

 

Were is it located? Please leave details.

Thanks alot
