DESY has two machines, European XFEL and FLASH. Both use almost same module and cavity types.During the module assembly many factors can deteriorate the cavity performance and cause a need for a repair action. Currentlytwo European XFEL modules and two FLASH ones underwent reassembly procedures. The repair was not immediately successfulon every of these modules and re‐iterations did follow. The degradation causes were investigated. SRF modules were tested onboth test‐stands at DESY: AMTF and CMTB. The results of the described actions are presented and discussed.
