Service Bulletin for Fuel Gauge

Hi, I have an 09’ C300 and randomly thr fuel gauge will show empty. I did have a DTC which was P0461 and I replaced the left side fuel level sensor which unfortunately did not fix the issue. The gauge will randomly do this and I might go 2 months with no issue or 2 weeks, no rhyme or reason. Does anyone know if there are any service bulletins for this issue. I don’t have access to wiring diagrams so I am unable to track down wiring

No service bulletin for fuel gauge that I have come across.

You do not give much info to go off of.

Have you tried a fuel additive like Techron to see if there is any difference?

What would Techron have to do with the fuel gauge not working?

Just a suggestion. May clean up any deposits in the gas tank. I have read where other people claim using Techron has solved there fuel gauge issues.
