First the 3 error lights came up on the dashboard, brake, Triangle and !. Read codes and says ABS/DSC . All wheel speed sensors are working properly. Then 2 weeks later I had a hard time starting the car twice leaving work. At first I thought it was the starter, but I went out to start the car 5x at different times and it started right up. I pulled codes again and have 7 faults.

 

Most of your codes are not present. How is your state of the battery? Battery terminals clean and tight? I'd suggest clearing all codes and start from there.

The only present error is that the rain-light-sensor connection is broken. Maybe a cable is broken, or fuse is gone?

 

Battery is only 3 months old and terminals are clean and tight. I also have a DME code and steering wheel airbag, DTC does not work, probably because of the other dashboard lights. Which code tells you that the Rain Sensor is not working?

You can look up the hex codes & their meanings here: https://bmwfault.codes/

 

Awesome.... I will look them up today.
