BMW 328i antifreeze warning light remains on despite full container on BMW 328i

Some BMW 328i owners report experiencing issues with the antifreeze warning light remaining on even when the coolant container is full. This problem may be attributed to a faulty coolant sensor that fails to send accurate signals, causing the warning light to stay illuminated. Additionally, some owners have encountered persistent warning lights due to underlying electrical faults within the system. To resolve these issues, it is advisable for owners to check the functionality of the coolant sensor and, if necessary, investigate potential electrical faults to ensure proper operation of the warning system.
