BC button not working
I have a 2002 325i and I changed the oil and when I went to reset the OBC so it knows I changed the oil. The post on the left side didn't work, the tip was broke on the inside. I fixed it, put it back together reset the oil, now the BC button doesn't work at all. It is stuck on the clock. When I was messing with it trying to reset the oil before figuring out it was the button, someone said to push auto and defrost at the same time, I did that too. Does anyone know how to fix it? I can get the test to work, I just want the temp, mpg, and other stuff back.
