Mercedes engines use 229.5, 229.52(replaces 229.51), and now 229.71 viscosity, so make sure if you don't want your Mercedes to be serviced by a dealer you purchase the right oil for your year and model.I'd be pretty pissed to be honest if my handbuilt in Germany engine by a specialist engine builder had a defect and a dealership tech has to tear it apart on the floor to rebuild it.
It should definitely be a swap. Also just seems inefficient and expensive to have a dealership tech open it up, then have bring in higher ups to review what the engine issues were, etc as opposed to sending it back into the factory for teardown and inspection. And then used as a core for warranty rebuilds.
