XY Ari is one of the few known eclipsing intermediate polars. We presentresults from a detailed analysis of an unpublished archival observation usingXMM-Newton EPIC pn and MOS data in a quiescent state of XY Ari. The X-rayorbital modulation and spin pulse variations were investigated for energydependent modulations in different energy bands. The broad orbital modulationobserved with various observations was confirmed with XMM-Newton at hard X-ray(>1.6 keV). The EPIC light curves folded at the spin phases show a double peakprofile as expected from two pole accretion. The pulse profile is found to beenergy dependent. Hardness ratio variations and energy modulation depth duringspin modulation can be explained by photoelectric absorption. Thesimultaneously fitted EPIC spectra with CEVMKL model yield maximum plasmatemperature of $28^{+3.1}_{-2.9}$ keV with an iron abundance$\mathrm{Fe}/\mathrm{Fe}_\odot=0.37^{+0.06}_{-0.05}$. We find two intrinsicpartial covering absorption columns of $6.2^{+1.0}_{-0.9} \times 10^{22}$ and$105.3^{+35.4}_{-30.4} \times 10^{22} \,\mathrm{cm^{-2}}$ with coveringfractions of $0.53^{+0.05}_{-0.04}$, $0.41^{+0.14}_{-0.13}$ respectively. Inaddition, a Gaussian emission line at $6.43^{+0.01}_{-0.02}$ keV with anequivalent width of $51^{+12}_{-10}$ eV is required to account for fluorescentemission from neutral iron. The X-ray luminosity of the source is $4.2 \times10^{32} \,\mathrm{erg \,s^{-1}}$ in the 0.2-10.0 keV energy band.
