[C320-list] Fuel Gauge Malfunction

[David Detrick]

Have a 2004 C 320 whose fuel gauge sometimes stays frozen on "E" after
starting, and then after running a while, pops up to the correct level of
fuel in tank. Several questions---

 

1.       What are possible causes-loose wire, bad sender, dirt in gauge,
etc.?

2.       How would you fix the problem?

3.       Could the problem affect the gauge reading properly when it pop to
a level above "E." In other words, can I trust the gauge?
