2013 Z4 Fault Code U0100

My daughter has a 2013 X4 i28. Originally I had two faults codes, P0072 and P0073 both of which indicate a problem with the ambient temperature sensor. I replaced the faulty sensor and those faults have cleared, but now I have a fault U0100 that doesn't show up in the shop manual. An online search says that the U0100 code means Lost Communication With ECM/PCM "A".

Does anyone know what the U0100 code means and how to remedy it?

Thanks
