Check Engine Light On?
BMW Check Engine Light Codes
Welcome to the BMW Check Engine Light codes page. The code definitions are a good starting point when determining the cause of the service engine light but where do you go from there?
When retrieving BMW check engine light codes with an OBD II scan tool, proceed as follows:
1. Connect scan tool to the 16-pin data link connector (DLC) located underneath the steering column. The connector may have a removable cover.
2. Turn the ignition on.
3. Follow scan tool manufacturer's operating instructions to access the Diagnostic Trouble Codes (DTC's).
Remember, these are manufacturer specific codes only. Refer to our Generic OBD II code list for definitions on all other BMW diagnostic trouble codes.
