In this work we extend the minimal gauged $U(1)_{L_\\mu-L_\\tau}$ model studied in \\cite{Bauer:2018onh} by a light (MeV-scale) vector-like fermion $\\chi$. Taking into account constraints from cosmology, direct and indirect detection we find that the standard benchmark of $M_V=3 m_\\chi$ for DM coupled to a vector mediator is firmly ruled out for unit DM charges.
