C230 Mercedez 2000August 7, 2014my gas level indicator isn’t working. The rest or the instrument panel is? 1 thought on “C230 Mercedez 2000” Freeautomechanic August 8, 2014 at 9:07 am The indicator is located in the fuel tank. First check to make sure the ground has a good connection before replacing the fuel level sending unit. Comments are closed.
