Rear shock bolt snapped
 

Had the lower bolt bolt snap off. Tried fluid, torch, welding nut on no help.
Any ideas how to get this out.?

I forget what it looks like on the E70. If it's what I think, you have good access to the bolt, right? Drill the center out and you can either use an ez-out or eventually peel the remains of the bolt out of the hole.

Yeah left handed drill bits are a great option.. they’ll often break the bolt free, and if not you end up with the bolt drilled out with just the threads to pick out of the hole. (Or then use an ez out)

I ended up changing the control arm. there was still 50 mm of bolt stuck in there and thats allot of drilling.

What part did you replace? Is it called a “swing part”?

yes it was the swing arm.
