I have installed the temperature sensor for the BMV712. It has measured temperature correctly for 2 months. But suddenly it shows about 20°C too low. When the temperature increases by 10°C, the number changes by about 10 degrees but still shows 20 degrees too low. I have restarted by loosening and checking the glass fuse. I assume that pure coincidence but the error was discovered when I via bluetooth changed settings with relay control from low SOC to temperature. However, I have tried to change back but no difference. Could the resistance in the sensor have broken, but if so the resistance must be changed which seems odd?
