Fuel guage not working!

Hello Fellow Motorists

I have a 85 728i euro model, with 121K. The fuel gauge never moves off empty, but the low fuel light works. All of the other guages work fine. Sending unit? Also, how does one reset the oil service light? Does it require a special tool? Happy Trails from a Noob to the forum.

Ola!

Hi there, Witeshark!
I'm up in St. Pete, coming down to the Glades in November. Is that sending unit accessible from under the backseat?

Under the rear seat you will find the loom that runs to the sender
carefully peel off the furry insulation.
Carefully pull out the big grommet being careful not to put too much pressure on the loom.
The foam insulation that covers the sender needs to be cut along the perforation with a sharp knife.
Now remove the domed cover over the sender using a Pozi-drive screwdriver.
Once the cover is removed use a paint brush to clean the area around and under the sender plate.
It is important at this stage that all the doors are opened, otherwise a build-up of petrol fumes could be hazardous.

The sender can be removed using an adjustable pipe-wrench , just a quarter of a turn does it.

The fuel sender wiggles out of the hole, do not apply any force as this wiggles out easily. If the area was clean, fitting the new sender is straight-forward, however, I spent a little time trying to keep dirt getting in the tank.

Hey Marti

The tips for resetting the oil service light and the inspection lights are for a later model, I don't have 22 holes in my diagnostic port.

Aww , shucks

thanks, Wite. That's new paint, the interior is just as nice, ivory leather with no rips or cracks, wish I had the original radio! A/c needs work , and I seem to have a power steering leak. No bad, for an 85. Now, I'll get those annoying service lights out.
