Edit: Re-read posts...The DME conducts a "pre-drive" test when the ignition is turned on before the engine is started. It cycles the actuators fully open and shut and detects any errors in position. So, the error code may be stored, but will not actuate limp mode if the test passes.

My code was 2B15 which apparently means throttle actuator governor bank 1. I replaced the actuator for the passenger side, which i assume is bank 1 per this DIY. And after I did it the problem is now worse. The actuator I got was used but supposed to be working properly per the seller. It came from a recycled 2010 M3.
