The strong interaction shift ε1sπD and broadening Γ1sπD in pionic deuterium have been remeasured with high statistics by means of the πD(3p − 1s) X-ray transition using the cyclotron trap and a high-resolution crystal πD πD spectrometer. Preliminary results are ε1sπD = (−2325 ± 31) meV (repulsive) and Γ1sπD(1171+23-49) meV which yields for the πD scattering length aπD = [−(24.8 ± 0.3) + i (6.3-0.3+0.1)] · 10−3 mπ−1. From the imaginary part the threshold parameter for pion production is determined to be α = (252−11+15) µb
