Hi ,my Tesla X P90D from 2016 has Low Collant level alert. I checked coolant level, but is correct. i Didn't notice any leaks. AC working correct , i think cabin heater also. I changed coolant level sensor 6007598-00-A, but no change. Test showed three failures: Battery heater, chiller , coolant level. It is any another coolant level sensor, or what i should change first to fix my problem. I will be very thankful for all advise.
