We describe a new technique used to measure the EDM of 129Xe with 3He comagnetometry. Both
species are polarized using spin-exchange optical pumping, transferred to a measurement cell with doped silicon electrodes, and
transported into the BMSR2 magnetically shielded room at PTB-Berlin, where SQUID magnetometers detect free precession
in applied electric and magnetic fields. Two campaigns in 2017 and 2018 have provided a combined statistical error approximately five-times smaller
than the most precise prior result published in 2001. Detailed study
of systematic effects including recent investigations of the sources of species-dependent drifts not compensated by the comagnetometer and the final combined result of the two campaigns will be reported.
