RTS engine includes components not manufactured by Rotax,
so it is obvious, that the warranty for the whole package must come
from Celier Aviation.
Rotax "approved" the RTS in the sense of allowing the modification
to their original 912 engine by adding 914 gearbox and turbo.
If they wouldn't allow it, they wouldn't sell the engines to CA,
knowing exactly, what they will do with them.
This way, or another, there is a warranty on the RTS engine
and it has a very good reliability record.
