I suspect a lot of early Diamond Austro owners wish that was the case. The block and internals seem up to the task (although they are supposed to be scrapped at TBO and not overhauled).
It's the accessories that have plagued the engine with problems as many, including alternators, fuel injection pumps, voltage regulators and dampeners, began failing well before expected/published service life limits. Some of this seems to be auto accessories that are not up to the demands of continuous high output aviation service.
One recent example is the fuel injectors. A mandatory service bulletin (that became an AD in Europe) came out in late 2018 putting a 900 hour service life limit on the injectors.

This is what the Bosch-made Mercedes injectors look like...quite different from those little things you get from GAMI for our Lycs and Contis. Each one is flow tested by Bosch and engraved with a number. That flow test number has to be entered into the Austro engine computer, to ensure correct air/fuel ratio, by authorized maintenance personnel who can access the software.

Some of the reaction at the time from owners wasn't all that positive.
Diamond/Austro seems to have persevered, attacked and steadily improved the overall reliability. But they have been an expensive engine for many owners to keep maintained, beyond any net gain from the fuel economy and airframe efficiency.
