I was attempting to change the spark plugs on my 2011 Cayenne s.  The first coil I attempted to remove (cylinder 5), I snapped the bolt.  I attached two pictures showing a close up and one farther out showing the coils for 5 & 6.  I haven't attempted to take the coil out and I'm not clear what I'm facing.  If I took the coil off, would there be a shoulder or something to get a vise grips on or am I looking at drilling a hole and trying to extract it?  

I also didn't attempt to take any other coils off for fear of breaking another one.  On the picture showing the coil for cylinder 6, this is ready to unscrew at this point and remove the coil, correct?

 

Any help would be appreciated.

By the way, can you clarify the procedure for removing the coils.  In my workshop manual, it specifically states a twist procedure to remove a couple of specific coils but the others just say "remove".  For cylinder 5 as an example, it just pulls out or you need to turn it or...?

I worked on this again and I cannot get that bolt out.  It snapped flush with the cover.  I tapped and drilled a hole for an extractor.  I get good bite with the extractor but it will not budge and I'm afraid I'm going to break the extractor off if I try harder.  I've tried heating it as well.  So now I'm not sure what to do.  Maybe take it to a machine shop?  I don't feel comfortable going larger with the drill bit and retapping as I don't know how much mass I'm working with around the screw.  Even though I used a center tap, I am slightly off center as well since the bolt snapped leaving one side slightly higher than the other.  Any other thoughts?
