I went to Azone and used the OBD tool. I pulled a sensor code. Went to BMW/Fairfax to get the new sensor. Replaced it and the SES light went out. Great.. But last night i get in and guess what. The damn light is on. Do i need to clear the code now? Also, my airbag light is on from when i unplugged it. Can i clear that somehow at AZone?
