Hello dear community, my name is Bernd I own a W123 240D and am new here in the forum, I have recently a problem. If the engine is cold, even at summer temperatures, the engine has hardly any power, as soon as it gets warm, so about 60 degrees, it runs completely normal and has the full power, while it does not jerk, runs calmly and does not smoke, also it starts in the cold worse, in the warm condition everything is great. last trip to the mountains. Maybe one of you has experienced this before or an idea what that can be. Thanks already ??
