Unhappy check engine light

My 2010 Z4 30i check engine light has come on. The car is 7 months old. The last time it came on was because I had been improperly replacing the gas cap each time I got gas. Recently I have been switching between normal/sport and sport+ modes. Has anyone had any check engine light issues with their Z4? I will be bringing it to dealership Monday morning.

Other than the gas cap, have you accidentally overfilled it with gas by chance? Kept pumping after the nozzle clicks off? That can possibly throw a CEL since it will screw with the evaporative control system.

Re Check engine light

The tank venting system was tested and the tank venting valve was replaced.

Thanks for the update! One of the reasons I've come to like BMW is the peace of mind for the first 4 years. Of course I have no idea what happens after that, but I think I'll find out in a year...

The extended care package for about $2000 covers 2 more years of service!
