OK, depth of empty hole is 1 13/16". Depth with broken bolt is 3/4. That's 1 1/16", minus the 19mm missing end, should be 5/16" left, so it shouldn't be bottomed.
With the tool in place, the good bolt starts threading at about 13mm / 1/2" from bottom of bolt head to the tool face, so there's that much thread engaged.
The bolt's outside thread diameter is about 6.5mm. The unthreaded shank is 7mm.
There's about 6" of free space from the head to the ABS lines below the master cylinder to fit a drill in. Might have to get hold of a short case or 90ยบ drill. The turbo hose and all that can come out of there.
A Volvo guy suggested a brass bushing or sleeve around the drill bit to center it on the bolt.
Noid - those hollow weld-thru bolts are a wild idea - I've never seen that. No welding capability here right now. On your third option, I just saw a video where he drilled the broken bolt but not all the way through, then ran a reverse tap into it, and by the time it bottomed in the bolt, it backed it right out.
I think the issue is going to be getting a drill in there, and somehow aligning with the threaded hole. Not sure how you'd get a punch in that small hole, 3/4" down in.
The threaded shaft holds a 10mm head (6mm?) bolt that clamps the position sensor ring onto those notches.
Also, it's 14 degrees in the garage and dropping. Almost 40 yesterday when I started.
