I have had one adaptive headlight malfunction warning light pop up on my 2011 135i. At the time of the event, I was driving the car hard at dusk (read: lapping). The malfunction light went away after I turned the engine off/on.
Car is still under warranty.
My dealership could not locate any DIAG errors or reproduce the issue, probably due to the fact that my Cobb PTF tune erases and clears the DTC's after any map changes or complete Cobb AP3 software removal from DME.
Any thoughts on the cause? Would vibration or hitting a large bump cause a warning light to pop on just like that?
