Between 2007 and 2017 comma our yearly XMM-Newton monitoring of SN1987A yielded EPIC and RGS spectra of unprecedented quality. The fluxes and broadening of the numerous emission lines provide information on the evolution of the X-ray emitting plasma and its dynamics. The soft X-ray light curve shows a mild flattening after 2006 and a flux decrease since 2014. To further monitor the evolution of the X-ray flux and to follow the expected turn-over we propose to continue our monitoring. This will allow us to further study the time evolution of the shock conditions and abundance profiles. At high energies EPIC-pn can help to clarify the extremely low observed Fe abundance by following the evolution of the detected Fe-K line.
