Two different codes, but kind of look like the same thing. They share the same "P" code.

Are you sure it is 279F? My BMW ISTA software does not show that code. It has 279E, but not "F".

Yes, definitely 279F

I found reference to output fan A, but I've no idea what that is

That is weird, since my BMW software is updated until 05/14... What's the production year of your car? Let me know and I will check some sources I have. Also, it is an E92 right?

Ok, I found it.

There are two descriptions for this code.

1. 00279F DME: Activation , Fan A
a. It can be the electric cooling fan that is not operating properly. How I would diagnose it? A primitive way to test it - if you do not have the BMW scanner or any other scanner that can activate the cooling fan and hear it functioning - would be turning the AC on and check if the fan kicks in. After some time, parked and engine running warm, you should hear the fan increasing the speed. The E92 M3’s fan is very loud when it is activated at maximum speed (hot weather and AC on).

2. 00279F : Map Thermostat Mechanism
a. The thermostat opens when the engine is too hot and allows the cooler fluid to refrigerate the engine. The car PCM (powertrain control module) monitors how efficient the coolant system is working. One plausible situation is, for example, when the engine is hot, the computer activates the electric fan and the engine does not cool down, the computer might interpret it as the thermostat is not operating properly. Also, the PCM (powertrain control module) might assume the fan is not operating as it should.
b. How to test it? Monitor the engine coolant temperature. It is difficult to do it on M3 because the instrument cluster does not have a gauge for engine coolant temperature, only engine oil temperature. But, If you have any scanner, you might be able to check the coolant temperature. It should be around 200 to 210 Fahrenheit when it is operation in normal temperature. Thermostat issues were very common on e46s. The computer than would register a code and the code description would be very similar to this one that you have (Thermostat Mapping Temperature).

I hope I was able to help!

Regards,
