Hello,

My 300D 1992 Estate does not read right on the gauge. Does anyone know how to adjust it with a full tank? At the moment it runs dry at 1/4 and reads fuel over 1/4 of a tank.

Many thanks

Martin

I think you must pull the sensor and carefully take it apart ....

I think your sensor axis is badly damaged, coverage is broken and wounded place stick junk, accumulate junk, float can not move freely along the whole axis ....

one of the pictures show black spots on the axis - there is hurt coverage ....

needs cleaning,sealing or worst - changing ....

One thing to keep in mind

I believe the wagons use a different fuel gauge than the sedans, but lots of folks swap in clusters at random. I've found that a sedan fuel gauge will not read correctly in my wagon. There might be a way to correct for this by adding or eliminating resistance, but I've never found out the particulars.

cleaned mine and even got a junkyard part, cleaned that one also, and it is still reading incorrectly, what should i do next?

thanks
Check the gauge and all connections. Search the forum and you'll find details on how to check/clean the gauge. There was a thread on the subject, " fixed the fuel gauge, not the sender."
