A fluid level sensor is located in the fluid reservoir of the cooling water, which activates the corresponding warning light in the instrument cluster if the coolant level is too low. This useful and important function requires a perfectly working sensor. In case of failure or the installation of a new fluid reservoir, we recommend the use of a new part.
The replacement is completed in one minute: Remove the plug, release the safety clip, replace the sensor.
The sensor is suitable for all W124.
