2009 Mercedes-Benz CLK-Class - Fuel gauge

Fuel gauge does not work after replacing sending unit.

did you have this problem before you changed it?
did you do the work? if not bring it back to where it was done.
if you did the work and were not having this problem, you need to recheck your work. maybe you forgot to reconnect something. check your fuses also.
now, if you had this problem before you changed it, this video might give you some ideas where to look. it is not your vehicle but should still be useful.
