Reduced engine power warning?
My 09 335i recently started displayinger warning" light. 96K miles and no mods except a Cobb tune. It seems that even while the warning comes on the car doesn't seem to be down on power. I've experienced that warning before when I've had a misfire and did realize a power reduction so I know what limp home mode should feel like but this is different. I haven't pulled the codes yet but I'm wondering if my HPFP is starting to go. Where should I start looking?

Take the entire car apart and have it fully restored.
Seriously? Start looking for a bmw-specific code reader and go from there. How are we supposed to know where you should start looking?
