HO thats no good i have done that a few times you could on the other ones try a impact gun and on low to mid settings sometime they come out, as for removing whats left they are a proper bugger there is a special tool for it lnk below there are cheaper ones but i have try'd them and very rarely will they drill straight,, one good tip is go to hardware store buy DRAPER EXPERT DRILL BITS i bought a set a while ago and they are border line un snap-able and dont go blunt, ie better drill bits than glow plug removal tools arehi all my wife has mini cooper d w16 1.6 hdi psa 2008 model, i have tried to change glow plugs but 2 have snapped at the tips and the other 2 will also break if pushed, i used plus gas for a week and engine was hot but to no avail.
has anyone on here tried the method of pushing broken tips in and extracting through injector hole by way of a wire and tiny magnet, im really not wanting to remove the head if at all possible.
