Heavy mesons are like jets one of the few probes which allow for studying the expansion of a plasma of quarks and gluons (QGP) created in ultra-relativistic heavy ion collisions. To do this we have to follow the heavy quarks from their production point through the QGP up to the final rescattering of heavy mesons with hadrons after the hadronization. In our approach the interaction of heavy quarks in the QPG is calculated in pQCD with a running coupling constant and including elastic as well as radiative collisions (arXiv 1307.5270). Combining the event generator EPOS with our heavy quark approach we can present event-by-event results in which the heavy quarks feel the fluctuation of the initial condition encoded in EPOS. We will present studies for pA in which also a (small) plasma is created to explore cold nuclear matter effects and an analysis of AA collisions. We discuss the origin of the elliptic flow of heavy quarks and the difference between the interaction of b and c quarks with the QGP. Special emphasis is put on the question of how the results depend on the effective degrees of freedom of the plasma.
