Check engine light on e90
My buddy's e90 suddently had his CEL come on after driving it this morning. The engine sounds rough at idle and seems to go away if I increase the RPM. I hooked up my OBC-II diagnostic tool to see what code would come up and nothing shows.
Is there a newer version of the OBC for 2007+? Unless it's some other engine fault that the OBC scanner cannot see and requiring a visit to the dealer or indy.
