The AMIGA enhancement (Auger Muons and Infill for the Ground Array) of the Pierre Auger Observatory consists of a 23.5 km$^2$ infill area where air shower particles are sampled by water-Cherenkov detectors at the surface and by 30 m$^2$ scintillation counters buried 2.3 m underground. The Engineering Array of AMIGA, completed since February 2015, includes 37 scintillator modules (290 m$^2$) in a hexagonal layout. In this work, the muon counting performance of the scintillation detectors is analysed over the first 22 months of operation. A parametrisation of the detector counting resolution and the lateral trigger probability are presented. Finally, preliminary results on the observed muon lateral distribution function (LDF) are discussed.
