Mercedes-Benz E400 engine won't start despite instrument lights appearing, possible low temperature issue on Mercedes-Benz E400

Some Mercedes-Benz E400 owners report experiencing starting issues despite the instrument lights being on, particularly in low temperatures. These problems may manifest as a clicking noise without the engine cranking, which could indicate a starter issue or a low battery. Additionally, some owners find that the EIS system fails to recognize the key fob in cold weather, preventing the car from starting due to its safety mechanism. Cold temperatures can also cause struggles with the electrical system or wiring, leading to fault messages on the instrument cluster. Furthermore, extreme cold may affect components like the transmission mount, resulting in noise and vibrations that disrupt engine operation. It is recommended for owners to address these issues to ensure reliable starting in colder conditions.
