We just recently got this car (2014 C250 1.8L turbo) and have had this happen a couple times when the temp drops. Worst was today. As soon as the car was started it listed off all the safety features that malfunctioned. Electric motion for the seats and steering wheel would not work. Lock unlock wouldn’t operate. Fuel guage would not register. I immediately got codes for each wheel speed sensors, vehicle speed sensor A, and lost communication with ABS system, codes are C0037,C003A,U0121,P0500,C0031,C0034. The car starts and runs ok. Idles about 1600rpm but the fan immediately turns on high. Mind you it’s 30deg F. It tells me traction control and all safety features don’t work and PRESAFE functions limited. I Shut the car down after capturing codes and had the wife take another car then Waited for later in the afternoon when the temps rose and it fired up with no issues. Beside the stored codes. It ran normal. I am having an issue where it says the hood is open. I did open it this morning to check on voltage but I’ve checked the switch and it seems to be operating as normal. Even bypassed the switch open circuit and closed circuit and still won’t go away. I’ve seen comments from others with similar issues where it will go away after you restart but normally it doesn’t give me a bunch of codes. Does anyone have any info they can share to help us out. This is my first Mercedes so anything will help. Thanks
