We propose observations of the southern disk of M31 comma which will comma together with our AO14 observations of the northern disk comma yield a deep full-coverage map of the hot ISM of the star-forming disk of M 31 on sub-kpc scales out to a radius of virgul10 kpc. The southern disk hosts the intriguingly large stellar association NGC 206 in the major ring comma where it was most likely disturbed by an encounter with the satellite galaxy M 32. New deep observations will enable us to 1closePar study the morphology as well as temperature comma density comma pressure comma and filling factor of the hot ISM comma in particular around NGC 206 and 2closePar probe the X-ray source population differences associated with the M 32 interaction by obtaining a complete sample of X-ray sources down to the confusion limit of a few 10elev34 erg-s.
