I have a 03' 326. The indicator is digital type located below the fuse panel for A/C. When indicator is turned on screen displays fuel, water and waste levels. What doesn't happen is movement. Water and wast display always resisters Low. Even when I fill up water tank or use the head, neither of the levels moves off Low. Power is getting to fuse panel and to indicator, where in line can I look for problem.

tank indicator

I'm assuming from your description that you have the "Snake River" panel. If so, it will have a calibrate function. This would be the first thing I would try. Depending on the year, the process for calibrating is a little different. The older ones were fairly intuitive and merely ask you weather you want to calibrate full or empty. The later ones had the calibrate function hidden. I'll see if I can find you a link with instructions. I don't believe this system is made anymore so if the problem is the display or the sensor you're probably out of luck. If I remember correctly, the sensor uses a conductive tape on the outside of the tank...make sure it hasn't fallen off. If it has, glue or tape it back on and it may solve the problem.
