Like he said - try tne EZ out again. Use PB Blaster to help break it loose. And check on how deep the hole is by removing one of the other studs (CAREFULLY) and sticking a toothpick or something in the hole until it bottoms out, and check the depth in the stud in question. If you can drill completely through the broken stud it will help because you can get the penetrating oil in underneath the critter, and wash away some of the rust holding it in. If you don't know how to get the stud out: use two nuts on the stud; tighten them together and then turn to remove. If it doesn't twist willingly, spray a little more blaster and with the nuts just a bit above the tip of the stud, rap with a light hammer while twisting the stud. And don't just turn to loosen, rock it back and forth until it moves freely. I have a buddy who can blast broken studs out of a head with an acetylene torch without damaging the threads (well, maybe a little) and you just chase them to remove debris.
I would put the new stud back in the hole in question, with a little threadlock. That is, after using something like Brakleen to degrease it. Reason? Come time to remove a stud again, it will not be corroded, and will release with a little heat. Broken studs are a problem for most guys working on Beetles who are impatient to get them out. I had the experience myself now and then, until an old timer showed me how to work them out. The Germans used a good quality steel, but not stainless. Of course, in 25,000 or 30,000 miles it is going to corrode, especially being in aluminum. After all, it was just a Beetle, not a Porsche... I have managed to remove studs, even with little or no thread left, without breaking them off since. But my buddy removed one for me that was broken off one time, with his torch. In aluminum, mind you. He had dropped the head on the old, brittle stud and it broke, of course... I was impressed.
