Check Engine light on

Hello,

Got a call from the wife telling me the CEL came on on our 2009 M5 GT at 13k miles. Did some looking around for anything loose, checked the gas cap but no joy. Will be making an appt with the dealers but perhaps someone might have suggestions on what else to check? Thanks.

Edit. Borrowed my friend's code reader and I got a P0455 - Evaporative Emissions Leak. Anyone have this issue? Is it something that I can replace or does it require a trip to the dealer? Thanks.

Stop @ autozone (& most other auto parts stores), they will read the code for you, free of charge.

There's no telling what's wrong without knowing the code.

I take it she didn't indicate any problems or noticeable differences in performance? Isn't there a gas cap light that's separate from the CEL? My Focus has a gas cap light so I'm just wondering.
 
Where is the obdii port? Just got a 2009 Sport and have a reader but haven't looked for the port. Would be nice to know is cel came on (but hopefully not - knock on wood).
 
The port is on the top inside part of the cubby that is to the lower left of the steering wheel.
 
Yea. Asked her if she noticed anything out of the ordinary like sputtering or hesitation, etc..but nothing.

A friend has a code reader for his mini. I'll ask him if it's mini specific. I'll post the code when I find out. Thanks everyone.

Is she sure that it's the check engine light and not, for example, a low tire pressure light?

Ich mchte auf den Autobahn fahren.
 
LOL. First thing I asked her when she called. Asked her to describe. Verified when I got home.

Yea. Nice driving the 5 on the a-bahn. The 5 is smooth and stable at 100mph. Even better with cruise con on.(drive)

An 09' with 13K miles should warrant a trip to the dealer for a warranty claim and a Mazdaspeed3 loaner car. How come you are avoiding the dealer?
 
That code says it's a "gross" leak, not a minor leak... I'd be willing to bet the gas cap wasn't put back on correctly, or at all. Clearing it will probably be fine.
 
Just a thought, could this error code be thrown if the vehicle was refueled without shutting the car motor off?
 
Not avoiding the dealer necessarily. If the CEL comes back, it'll be going to the dealer. Based on my forum research and wife's testimony that she may have not tightened the gas cap the day before, decided to clear the code. AFAIK, they don't do loaners in Germany. At least not with BMW, Ford, Mazda, and Toyota. They'll provide a rental.
