The origin of Fast Radio Bursts (FRBs) is still unclear with a plethora of theoretical models for their origin. Several such models predict associated multi-wavelength emission, but previous searches for optical, X-ray or gamma-ray counterparts of FRBs have not led to any detections. The Galactic magnetar SGR 1935+2154A has been observed to simultaneously emit FRB-like bursts and X-ray flares. We present a joint radio/X-ray program using the eROSITA instrument and the Effelsberg and Parkes radio-telescopes to conduct simultaneous radio/X-ray observations of previously detected FRB positions. Low-DM and repeating FRBs make excellent targets for these coordinated observations aiming to observe coincident radio/X-ray flares to determine if this phenomenology applies to the extragalactic FRB population.
