Yea this seems to be happening alot lately. happened to the E90 boys over at E90post.com but that was basically due to their higher boost levels. i would do what "0bD" said and remove the mods. i would try the dealer but they'll know everything you did with it mod wise. since the 535i uses the same engine as the 335i, the DME stores all information including boost pressure. it's so sentive, that it detects if you changed a bulb. so when the techs pull the car on the Diagnostics reader, it's gonna show abnormalities that BMW doesn't normally see. which leads to their investigation of vehicle tampering. best way is to remove mods, and see where that goes after a reset. if that doesn't work carry it by the dealer. hopefully you'll get away with it and not a pay a dime.

Limp mode is not uncommon at all. Like previous posts have said the E90/E92 guys have been experiencing this, especially on modded 335i's.
It also isn't uncommon to happen on unmodded or stock 335i's.
During the Motor Trend G37s vs. 335i comparo. The 335i went into limp mode on their test track.

Because the reduced power has been activated during normal driving conditions, oddly enough, not during spirited driving, I'm leaning toward an existing condition before mods. The fact that the mode was activated shortly after I installed the SSTT and changed to race gas may be a coincidence since I installed the mods 2 weeks after purchasing the car as a CPO car. There have been times that 1-2 weeks have passed without a code.
This is a good one for the tech heads in our readership!!
