In this article, we study Langevin diffusion coefficients for the five-dimensional $\mathcal{N}=2$ STU model in the presence of higher derivative corrections. We obtained the effect of black hole charge, corresponding to the chemical potential, on the Langevin diffusion coefficients ratio. We confirm universal behavior of transverse-to-longitudinal ratio of coefficients.
