Rotax themselves made the engine in question unqualified for night by

Does anyone know if there was a technical reason for the restriction?
The general feeling on the Rotax boards that I was reading at the time
(I was considering one for my 601XL) was that it was pure CYA for liability.

This seems reasonable, considering the few changes between the 912ULS and
the night, IFR-certificated 912S...it wouldn't surprise me to discover most
of the $8000 price difference between the two goes to a liability insurance
fund.
