Good day, I’m new here in forum, have already researched a lot, but unfortunately not found the right one. I have a SL 500 R230 BJ 2004 130,000 km. The vehicle cannot be opened in cold, neither via the key nor via the Keyless Go card. If I then take the emergency key and open the vehicle, the alarm system immediately goes on. If I then put myself in the vehicle and want to start it, the car does not recognize the key (you can’t turn it in the lock) keyl The battery of the SL is also not empty, has been bought anew and was also charged the day before. I am also a danger the day before about 50 KM. Yesterday it was from noon about 18 degrees and the car can be opened easily ( via key and keyless Go). The vehicle goes on quite normally (electric consumer is also not shown). (In the morning it was 5 degrees and it was not possible) That has surely happened to me already 10 times and it is located It’s definitely about whether it’s cold or warm outside. Can’t explain it to me. (I don’t mean -20 degrees with cold, but about 5 degrees) My consumer battery is completely empty even after about 10 days when the vehicle is standing. However, the Mercedes workshop has not detected any power consumption over 2 days. Batteries of keys and keyless go card are also new, so that’s not what it is. Today the vehicle went up, but the warning flasher flashed and g In addition, the speedometer has failed again and again. But the whole thing was over after 5 min drive as if nothing had ever been. Unfortunately, I don’t know any more and hope someone can help me here. Thanks in advance.
