When I check the codes with my BT software I get 283f, 278b, 27c3, 27de (oil pressure switch: signal implausible, temperature sensor engine cooling, thermostat oil level sensor, temperature sensor engine coolant: signal). Coolant and oil are full and seems to be running well, no overheating. The problem seems to be getting worse (more frequent).

The coolant temperature sensor, as the name shows, is used to indicate the temperature of the coolant in the car. The reason for the exiting of the coolant temperature sensor is for engine running in a proper temperature range. This part is listed by BMW as BMW part number 13621433077 (13-62-1-433-077) and is described as Coolant Temperature Sensor.

This OEM coolant temp sensor is located in the lower radiator hose (or in the radiator) on most models. It sends coolant temperature to the ECU which controls the thermostat and electric auxiliary fan. Code 278B points to a problem with the coolant temperature sensor, while code 279B signifies an issue with the thermostat.

The coolant temperature sensor is tasked with relaying information to the engine control module (ECM) regarding the temperature of the engine coolant. The coolant sensor plays a crucial role in monitoring the engine's temperature and ensuring that the cooling system operates efficiently. A malfunctioning sensor can lead to a cascade of problems, from overheating engines to poor fuel efficiency, making it essential for drivers to be aware of potential issues.
