The European X-ray Free Electron Laser (XFEL) superconducting accelerating modules, containing a string of Niobium (Nb) cavities and a quadrupole, will operate at 2K. In this paper, vibration stability studies of a high gradient XFEL/FLASH type III+ superconducting accelerating module with its quadrupole operating at 2K for the first time and with the latest design of the cryogenic inner layout will be reported. These measurements are possible using geophones which operate at cryogenic temperatures in both horizontal and vertical directions. In addition, investigation of vibration stability in relation with positioning the quadrupole in the center or the middle of the modules will be presented.
