Do you have a generic OBD II reader/scanner that can retrieve the generic 5 digit DTC (diagnostic trouble codes)...or another (upgrade) scanner that may have its own OBD II code table? If not...do you have any app (like Bimmerlink) that can retrieve the OBD II fault code(s)?

Keep in mind that the CEL on modern cars can also trip for manufacture specific codes as well as the required emissions codes. So his issue could be BMW/X7 specific. That said, without some type of code reader, preferably one that can also read BMW specific codes, it will be impossible to know what is going on…
