Abstract We present a measurement of diffractive D* meson production in deep inelastic ep scattering. These events are of the type ep->eXY, where X contains at least one D* and is separated by a large rapidity gap from the system Y of the outgoing p. This gap is used for the diffractive event selection. The measurement is performed with the H1 detector. The results are based on a data set recorded in 1999 and 2000 with three times larger integrated luminosity than in a previous publication. We show differential cross sections and compare them with different models.
