The ME IR checkride consists of the same as the SE IR checkride with an added simulated single engine approach in the twin.
I have the impression that the SE IR check ride was a lot tougher on the IR part.
The IR-part of the ME check ride is mainly (solely) the simulated single engine approach.
I guess theoretically they could throw a partial panel at you during the simulated single engine, but I've never heard of that.
