We calculate dilepton production for the reactions $\\pi^-$C and $\\pi^-$Pb at 1.3 GeV within a semi-classical BUU transport model and compare our results to a previously published calculation. We show that a modified treatment of the We, furthermore, discuss uncertainties related to the electromagnetic decay of the $\\rho$-meson and the elementary $\\pi^- N \\to e^+ e^- X$ channels.
