What's the 2f0d BMW code?

A BMW diagnostic trouble code of 2F0D translates to Radiator blind, input signal GLF. The "blinds" are the air doors on the radiator, and this code is triggered by a failure condition reported by the sensors for those to the engine control module. (ECM). However, this can also be an erroneous code, and is fixed by a software update, available at Your local BMW dealership. If the code actually is legitimate, then You've likely been experiencing some engine over-heating at this point, which is a symptom of this condition. You may have also noticed that the radiator fan is running a lot more often, or seems to be louder, which is also related to the error code.
