DME 2F71 ans 2C92 diagnosis faults

[aureliogut]

Good.
Last week I experienced a rough running of the engine, similar to an injection failure in my Z4M coupe. After a long day of travel, about 8h.
I have looked at the diagnostics and found 2 faults.
2F71 electrical device box fan.
and 2C92 exhaust temperature sensor.
Has anyone had these errors?
The sensor is easy to change but the fan could be a more complicated fault to solve?
Thank you

I've had the 2c92 egt sensor code, easy to swap out, just make sure you buy the correct one, USA is different from euro.

thanks. I see is easy to change.
i´ve tryed the car 3 times after the motor fail, and the motor worked well.
I think the problem is an electronic component which heated and made a bad signal.
maybe wouldnt happen againg if i dont drive for many ours, but ill try to repair the fan code.
