We present new analysis of the X-ray spectra of the Seyfert 1 galaxy NGC 3516 as seen by the XMM -Newton RGS and EPIC -pn in recent observations, with the emphasis put on high resolution spectroscopy. NGC 3516 shows interesting spectral and flux variability during four observations in 2006; we investigate whether this is due to absorption by the warm absorber and/or is intrinsic to the source emission. We show that the passage of an absorbing cloud, part of a clumpy disk wind model, is unable to account for this variability. Intrinsic changes in the source continuum are found to play a much more significant role in explaining the observed flux and spectral variability than originally thought for this AGN .
