Check Engine Light - Recommended Higher Octane Gas
Hey Everyone - I'm somewhat new to this forum and need some assistance. I have a 06 M6s with 83k miles. The CEL light has been going on and off for the past 2 weeks. I had it checked out and they recommended higher octane fuel. I was originally using regular (87) and filled up with plus (89 I think). The light keeps going on and off. There is no noticable difference in driving. Unfortuntely I didn't write down the codes. Any suggestions? Has this happened to anyone else? Should I try premium gas?
I'm not a big car guy but always want to make sure my cars are running well. Any help is appreciated.

Well, as I was told in the past, running a different octane (AKI in the U.S.) will make no difference in performance... and it is true. Who ever told you to run higher "octane" gas to clear a code obviously doesn't know what they're talking about... oh by the way I have some beach front property for sell in Colorado... just kidding!! get the codes read and go from there... and write them down!!!

Said another way, find yourself a competent service center and use them.

there isn't much that u can do until the CEL stays ON so that the code scanner can read the code. Not to worry as long as there is no issues like low fluid levels or engine misfiring

most common causes of that is an exhaust leak, bad 02 sensor, intake leak after the maf, or maf senor is bad. you need to take the car to someone who actually knows something so they can run some simple diag. im usually not that rude to others but the person you took it too the 1st time is a complete idiot, if he/she does not know what they are talking about they should ask someone who does and not lie to your face.

What they ALL said.
Higher octane will not solve the problem. Higher octane requires higher compression, and/or different (re: more aggressive) valve timing, OR a boosted (supercharged/turbocharged) engine, which you don't indicate, to burn properly and completely. With an engine designed to run on 87, it will burn slower and therfore some of the raw, unburned fuel will be exhausted. This is hard on other parts... typically the catalytic converter which are likely to be used up sooner using higher octane than the engine is designed to burn. It has to work harder to perform it's job.
Your mechanic/code interpreter is incompetent.
You've got another intermittent problem, could be as sinple as a dirty MAF sensor.
They are known to be finacy. Try removing it and cleaning it first.
