Try switching on the APR before the needles line up. That way the sim has
enough time to make the intercept.

When I use the Cessna Caravan and other planes and I use ILS
approach and follow instructions for staying at a certain altitude,
and heading until the localizer needles are lined up and then switch
to the APR button the plane goes haywire and dives for the ground. Is
this a known problem. Both needles are dead center when this happens.
