Hello everyone, I recently purchased a 2007 Saab 9-3 4cyl FWD with 72k miles on it. Upon starting the car I get the service soon on the dashboard. This lead me to insert my code reader. I got the code U2105. I am aware this could mean a bad ECM or Traction Control Failure. The car starts and runs great. Others tell me it's probably just a code they forgot to clear or maybe it's just a bad wheel sensor, does anyone else have this problem or can I get some feedback on what this could mean.
