Yes, there are actually a couple of possibilities. The sending unit in the fuel tank and the gauge itself in the instrument cluster. Much of this can also be tested with a scan tool and many parts stores loan out this toll for just a deposit.

Please understand that I don't know your skill level or tools
you have to assist us. Also understand that I can't see, smell,
hear, or touch the vehicle either, so your patience is
appreciated. JA is a great Q/A site, but it does not replace a
repair shop. So please don’t shoot the messenger if I have to
deliver bad news:)
If you are satisfied with my answer, I would greatly
appreciate a 5 star rating now before you leave the site and I
will still assist you after you have rated me too if another
question pops up. I don’t get credit for helping you until
you rate me

Thanks, Ron

If the problem is in the fuel sending mechanism , will the tank have to be pulled ? also, problem in intrument panel , is it as simple as replacing a fuse ?
Mercedes Mechanic: rpmdiag, Tech and Instructor replied 11 months ago

If it's in the tank, the tank has to come down.

If it's the gauge, the cluster has to come out.

The test will show which is the problem.

Thanks again and please remember to rate me 5 stars now
and keep this link in case you need me again later on.
I don’t get credit for assisting you until you rate me
