2001 X5 with 3.0. 85k, I am recently experiencing an intermittent “Service Engine Soon” light coming on. Engine had some gunk in (serviced since brand new @ the BMW dealer!) it when I opened oil filler cap, so I flushed the engine with clean oil (no additives) and converted to the Amsoil about 4k ago. Since about 2k ago engine light started to show up, primarily when I am about to “run out of gas” may be little less then ¼ of the tank. Could my oil change “improvement” had something/anything to do with it?
Thanks for all your help!

You could of possibly turned your car on before your gas cap was put back on. That can cause an intermittant check engine light. If you take it to your dealer there likely charge you an hour labor to delete the fault code.

Thanks a lot for your suggestion.

What about getting my own ODB II scanner? Does anyone have a recommedation? I'd reather by one that can handle my Toyota, Volvo and BMW. I know you can go to the Atozone and rent one, but from previous experience it's not worth the hassle.

thanks,

Then what could it be? I bought a code reader but the plug would not fit :banghead:
So which one does and what the best buy for the money?

Thanks!

Thanks!Any OBD2 scan tool will have the right connector for the interface under the dash

by the way, the vast majority of intermittent chack engine lights are camshaft, or oxygen sensors
