This morning I took top mass osem spectra for both PR2 and PR3 suspension and they looks healthy (the noise level for all bosems are similar and the magnitude is to below 10^-4  above 10Hz - un-calibrated) - plot attached below. There is a 15Hz peak seen on PR3, which is also seen (in both PR2 and PR3) if we go back in time (7 days) compare the spectra results. 

I also looked at the medm screen of both the suspensions (input filters, flag position, damping loops and coil driver settings) and trended bosem channels and did not find anything unusual.
