RE: E30 sending unit/fuel gauge

["Stuart Logan" <stu64@xxxxxxxxx>]

Check the wiring between the sending unit to the gauge, especially in the
drivers kick panel and under the carpet next to the door.  I had this same
symptom with a recently acquired 528e - turned out to be just a few bad
wires.  The Bentley is pretty good at showing the colors and sizes of the
wires to look for.  Be Patient and Good Luck!

Subject: E30 sending unit/fuel gauge

fuel gauge on 91 325i displays full constantly. I removed sending unit,
tested with ohm meter. It indicated proper 3.5 ohm reading at empty, and
resistance
increases as float rises, but max reading at upper float limit is around 58
ohms. Bentley doesn't say, but old Haynes manual says full tank ohm reading
should be around 78 ohms. Would this difference in full tank reading confirm
a
bad sender? Seems to me that if resistance readings on lower float positions

seem to be indicating sender function, fuel gauge indication wouldn't be
staying
on full. Any guidance on this? Any tips on troubleshooting fuel gauge.
Thanks.
