Fuel gauge issues

Did you measure the Ω on the sensors when you cleaned them?

When mine acted similarly I had to disassemble and bend the sweeper in such a way to increase the pressure but also when done you need to reset the computer with option 21 in the hidden menu or the "averages" will throw it off. With any luck you are just seeing the math error.

Start with option 21 that might be your only issue. Confirm with option 6 to make sure the liter readings left and right are reading correctly.

When my right sensor stopped reading I didn't realize for a while because I only filled partial tanks for a while. Then when I did fill completely it only showed 2/3 to 3/4 full.

After I fixed the sender it still showed only 2/3 full until I reset with 21.
