I was just wondering if I should be concerned that my fans are running at full and the check engine light is on. I just noticed it about a week ago and have been driving it fine since I didn’t get any codes. It first started when I left the car out in below 20 degree weather and snow. I read that it could be a water pump issue but I haven’t got any codes and it’s driving fine. I have a 2012 135i on Mhd stage 2.
