This paper concerns the simultaneous effect of homogenization and of the small noise limit for a 2nd order mean field games (MFG) system with local coupling and quadratic Hamiltonian. We show under some additional assumptions that the solutions of our system converge to a solution of an effective 1st order system whose effective operators are defined through a cell problem which is a 2nd order system of ergodic MFG type. We provide several properties of the effective operators and we show that in general the effective system looses the MFG structure.
