L dwarfs in close binaries openParperiod virgul100minclosePar with white dwarfs are rare although expected to be the majority and representing the end stages of cataclysmic variable evolution openParperiod-bouncersclosePar. The detection of X-rays from WD - L dwarf openParWDLDclosePar binaries is an efficient diagnostic of accretion since L dwarf coronal emission is below the sensitivity of current instrumentation. XMM-Newton is the only facility able to study these faint comma moderately soft X-ray emitters. In AO14 we detected X-ray orbital modulation in a known magnetic short-period WDLD system comma thus setting a tight constraint on the mass transfer rate. We here propose to continue our survey observing the only other 2 magnetic short-period WDLDs aiming at understanding the evolutionary stage of such systems.
