It means your car has the obd2 code problem, the first you need is to check out the code and then delete/reset it. I know this tool is helpful for your car. http://www.chinasinoy.com/wholesale/bmw-gt1-dis-v57-sss-v39-compatible-with-all-computer-1252.html Or you can take your car to the local dealer to diagnose out the code, then they will tell you how to fix it.
