[oe_tuning]

hi guys....

i got a question on my fuel gauge:
this thing is moving up and down constantly, like one minute its 3/4 and then ten minutes later its less than 3/4 and then it goes higher than 3/4

what can be wrong about this?
is there an easy (and cheap) fix for it?

thx!!!

Common problem.

Incorrect Fuel Gauge Reading
Model:
BMW E36 (3 series) including BMW 318ti produced from January 1995
Complaint:
Due to the formation of a non-conducting deposit on the conductor surface of the fuel level sensor, the fuel gauge does not read full after re-fuelling, or the fuel gauge is erratic. Remedy:
Remove and replace both fuel level sensors with “Gold system” sensors.

Fuel Gauge Stays Empty after Refuelling/Fuel Gauge Erratic
Model:
BMW Z3 Roadster/coupe, BMW M roadster/coupe (E36/7). Vehicles produced before December 15 2000
Complaint:
After refuelling the fuel gauge will stay on empty or the fuel gauge is erratic. This is caused by a non-conducting deposit being formed on the conductor surface of the fuel level sensor. For the Z3 from September 1998 and the M roadster/coupe FC 2 (Fuel sensor voltage plausibility) will be set in the Instrument Cluster.
Remedy:
Remove and replace the fuel level sensor with a ‘Gold system’ sensor referring to repair instructions 16 12 000.
