Our C3 is a 1.4HDi SX 50kW. With my tank display I always have a fault. Although the tank is full, the display starts to flash and to beep like when jumping on reserve tank. Here is a video of the problem: https://www.youtube.com/watch?v=hmX6QtZjV_c I could fix it then for several months by adding winter additive, but last autumn it appeared again and comes sporadic again and again. It will probably be the sensor defective (glued float) The problem is quite annoying because sometimes the error appears again and again during a trip and then you have 10 minutes nerve-killing long-term beep. I have already googled myself quite crooked, also in French forums (fleteur de reservoir, jaugeur, level de essence, capteur etc.), but have found so far no information where the part is located let alone a removal instruction. Does anyone here possibly have a plan? Is the part possibly under the bench? Thanks in advance for all the tips!
