Resistivity and Hall effect measurements of EuFe$_2$As$_2$ up to 3.2\,GPaindicate no divergence of quasiparticle effective mass at the pressure$P_\mathrm{c}$ where the magnetic and structural transition disappears. This iscorroborated by analysis of the temperature ($T$) dependence of the uppercritical field. $T$-linear resistivity is observed at pressures slightly above$P_\mathrm{c}$. The scattering rates for both electrons and holes are shown tobe approximately $T$-linear. When a field is applied, a $T^2$ dependence isrecovered, indicating that the origin of the $T$-linear dependence is spinfluctuations.
