My Teltonika FMC003 is reporting weird (OEM) fuel level values which I can’t make sense of. My car is a Mercedes C-Class mk4 (W205) (2015-2019) which is found in the compatibility list and appears in the configuration options.
My fuel tank capacity is 66 litres and according to Mercedes Me cloud service (right picture) it is 53% full and this also aligns with my the fuel gauge on the car dashboard. So doing the maths, it should have about 35 litres in the tank.
However, the Teltonika FMC003 is reporting 78 litres (left picture). I’ve tested a few different scenarios but I cannot figure out what is going on. The ODB fuel number (litres x 0.1) reported by the FMC003 is illogical.
Note, the OEM mileage (11,5537 km) is correctly reporting. The issue is only with the OEM fuel level.
Looking forward to some guidance and help.
