We investigate whether a self-interacting Brans–Dicke theory in without matter and with a time-dependent metric can describe, after dimensional reduction to
, the FLRW model with accelerated expansion and non-relativistic matter. By rewriting the effective 4-dimensional theory as an autonomous 3-dimensional dynamical system and studying its critical points, we show that the
CDM cosmology cannot emerge from such a model. This result suggests that a richer structure in
may be needed to obtain the accelerated expansion as well as the matter content of the 4-dimensional universe.
